14 Awesome Arduino Cloud Features You Never Knew Existed

Tweet

There are dozens, if not hundreds of amazing Arduino Cloud features. So it’s perfectly understandable if you’ve missed some of them.

So we’ve put together a list of our favorite Arduino Cloud features that you might not know existed.

1) Auto-generate Sketches

We’ve talked elsewhere about getting an understanding of what cloud computing really is, and how it’s not just the domain of experts. The cloud is how total beginners can get started much more easily. There’s no better demonstration of that than our first top Arduino Cloud feature; auto-generated sketches.

When you create a new “Thing” in your Arduino Cloud, you add various bits of info to it. Wi-Fi connection credentials, and any variables you want to control or monitor. The Cloud automatically generates a starting sketch from this info. That sketch can then be sent to your boards, so all your initial configuration is taken care of, without a single line of code.

2) Device-to-Device Communication

There’s simply no easier way to make two microcontroller boards talk to each other than Arduino Cloud. We’ve covered in detail how easy it is to wirelessly connect your boards.

This isn’t just for Arduino devices either. If you want any combination of Arduino, ESP32 and ESP8266 devices to work together, this is how you do it.

3) Over-the-Air Updates

Working through your Arduino Cloud means you don’t have to disconnect any Arduino boards when updating them. If you want to edit or add a new sketch, it can all be done wirelessly, over-the-air.

Anyone who’s had to dismantle a project or device to get to a board’s USB socket will appreciate the simple, vital value of this feature. It’s one of those things that you’ll wonder how you ever lived without.

4) Support for ESP Boards

There’s a reason we call it the Arduino IoT Cloud. This is an all-encompassing platform for Internet of things, home automation, and electronics project control and management. So first we added support for ESP8266 devices. More recently, experimental support for ESP32 boards became available.

So even if your project doesn’t actually have any Arduino products in there, the Cloud is just as useful. Secure, private, and accessible to all kinds of IoT and maker devices.

5) Trigger Actions on Cloud Events

Arduino Cloud makes it super easy to do things that you might normally need the IDE for. But it’s also got lots of exclusive features that you only get in the Cloud.

For example, there are actions that can be triggered based on your board’s interactions with your Arduino Cloud. You can include actions within your sketches when a Cloud connection is successful, and when the Cloud has synced with a device. Or perhaps most useful of all, trigger an action if Cloud connectivity is lost. Getting an indication that a project has disconnected could be incredibly useful!

Here’s an example of using these actions within a sketch.

6) Sharing Your Dashboards

Dashboards are control panels within your Arduino Cloud. It’s one of the most powerful Arduino Cloud features, and essential to making full use of Cloud control. But what’s often overlooked is that you can share dashboards with anyone you want.

For example, let’s say you’re using Arduino Cloud to control your home automation. You can set up a dashboard for a tablet in the living room that the whole family can use, but doesn’t have sensitive admin controls in there. And then another for people to use on their phones. 

All Cloud plans include unlimited dashboards. And anyone can have a free Cloud account. So you can create as many dashboards as you like, and share them with literally anyone, anywhere.

7) Alexa Integration

Natural language voice control is genuine Star Trek stuff. So it’s no wonder people love the functionality of Alexa. Did you know it’s incredibly easy to connect your Arduino Cloud to Alexa? And once you have, it effectively adds voice control to every board, and every project. Nothing else needed.

There’s literally no easier way to make an Alexa-controlled device or project than with your Arduino Cloud. You’ll never look back, and you’ll always have someone to talk to.

8) Full API Integration

For the engineers, coders, developers and those among you who’ve been using Arduino for a long time, API integration is the powerhouse secret feature you’ve been looking for.

The API can be called with any HTTP client, or with languages like Javascript, Python, Golang and more. It’s what you need to incorporate the power of Arduino Cloud features into your systems, platforms and projects.

9) Use IFTT, Zapier and More with Webhooks

There are lots of reasons you might want to include control platforms outside of your Arduino Cloud. Like sending an email or a Tweet when you press a button on a Nano, or a device disconnects from the Cloud (see above).

That’s what webhooks are for, and they give you a universal way to send commands out of Arduino Cloud, and into… well, anything!

IFTTT and Zapier are great examples of services that can do almost anything from a webhook. Get to know this feature, and connected projects suddenly have easy access to the whole web.

10) Easy Firmware Updates

When you connect a new Arduino board, your Arduino Cloud automatically checks its firmware version. If there’s an update available, it offers you the option of applying that update.

Very easy, and you don’t have to worry about finding the correct/latest firmware version yourself. This simple, background function makes sure your boards and projects always have the latest features, security updates and bug fixes.

For people who use a lot of Arduino devices, it’s worth adding them to the Cloud for this feature alone.

11) Full Dashboard Customization

We’ve already talked about unlimited dashboards in your Arduino Cloud. Creating them is easy, but did you know you can customize them too?

Anyone who’s dipped their toe in the home automation waters knows how essential dashboard editing is. Some platforms work great, but offer very little when it comes to controlling your dashboard layout. For many people, that’s a deal breaker.

Your Arduino Cloud widgets can easily be added, edited, removed, repositioned and resized in any configuration you want. It’s as simple as drawing and resizing boxes, but the result makes your Cloud projects infinitely more useable.

12) Watchdog Timer

The Arduino Cloud automatically runs a watchdog timer that will reset your board, hardware or project if it crashes. This is a small feature, but a powerful one that can keep your projects running while unattended. 

It means you never have to manually reset it when you eventually realize it’s not been running all day. You can have devices running remotely (very remotely, with SIM or LoRa connectivity) and be sure they’re robust enough to keep on ticking.

It’s included and running automatically, but can easily be disabled if you don’t need it.

13) Node-RED Integration

Arduino provides a super easy way to use Node-RED for IoT automations. This is a powerful, but very easy-to-use visual programming platform specifically designed for IoT projects.

Complex automations using advanced triggers like sunrise or sunset, presence detection, combined actions or sensor readings and so much more. The possibilities are endless, and learning Node-Red is incredibly easy. Get to grips with this feature, and you’ll be creating IoT automations that would otherwise need an experienced coder.

13A) Fully Functional Free Account

One of the best kept secrets of the Arduino Cloud is that if you’re registered on the Arduino website or forum, you already have a free Cloud waiting for you. Simply head on over to the Cloud site and get started with unlimited dashboards and unlimited sketches. The free tier of Arduino Cloud is fully functional, and it’s ready and waiting for you to give it a try.

In fact, it’s the perfect option especially if you haven’t used Arduino before! Give it a shot and let us know what you think. No credit card required; just your creativity and a passion for connected projects.

Ubidots + ESP32- Predictive Machine Monitoring

Predictive analysis of machine vibration and temp by creating mail events and a record of vibration in google sheet using Ubidots.

Story

Predictive Maintenance and Machine Health Monitoring

The rising of new technology i.e, the Internet of Things, heavy industry has started adopting sensor-based data collection to solve its biggest challenges, principal among them process downtime in the form of shutdowns and process delays. Machine monitoring also called predictive maintenance or condition monitoring is the practice of monitoring electrical equipment through sensors in order to accumulate diagnostic data. To achieve this, data acquisition systems and data loggers are used to monitor all kinds of equipment, such as boilers, motors, and engines. Following condition are measured:

Temperature and Humidity Data Monitoring

Current and Voltage Monitoring

Vibration Monitoring: In this article, we will read Temperature, vibration and publish the data in Ubidots. Ubidots supports graphs, UI, notifications, and emails. These features make it ideal for predictive maintenance analysis. We will also get the data in google sheets which will make predictive maintenance analysis more easier.

Hardware:

ESP-32

IoT Long Range Wireless Vibration And Temperature Sensor

Long-Range Wireless Mesh Modem with USB Interface

Software Used:

Arduino IDE

Ubidots

LabView Utility

Library Used:

PubSubClient Library

Wire.h

Arduino Client for MQTT

This library provides a client for doing simple publish/subscribe messaging with a server that supports MQTT

For more information about MQTT, visit mqtt.org.

Download

The latest version of the library can be downloaded from GitHub

Documentation

The library comes with a number of example sketches. See File > Examples > PubSubClient within the Arduino application.Full API Documentation.

Compatible Hardware

The library uses the Arduino Ethernet Client api for interacting with the underlying network hardware. This means it Just Works with a growing number of boards and shields, including:

Arduino Ethernet

Arduino Ethernet Shield

Arduino YUN – use the included YunClient in place of EthernetClient, and be sure to do a Bridge.begin() first

Arduino WiFi Shield - if you want to send packets greater than 90 bytes with this shield, enable the MQTT_MAX_TRANSFER_SIZE () option in PubSubClient.h.

Sparkfun WiFly Shield – when used with this library

Intel Galileo/Edison

ESP8266

ESP32The library cannot currently be used with hardware based on the ENC28J60 chip – such as the Nanode or the Nuelectronics Ethernet Shield. For those, there is an alternative library available.

Wire Library

The Wire library allows you to communicate with I2C devices, often also called "2 wire" or "TWI" (Two Wire Interface), can download from Wire.h

Basic Usage

Wire.begin()Begin using Wire in master mode, where you will initiate and control data transfers. This is the most common use when interfacing with most I2C peripheral chips.

Wire.begin(address)Begin using Wire in slave mode, where you will respond at "address" when other I2C masters chips initiate communication.

Transmitting

Wire.beginTransmission(address)Start a new transmission to a device at "address". Master mode is used.

Wire.write(data)Send data. In master mode, beginTransmission must be called first.

Wire.endTransmission()In master mode, this ends the transmission and causes all buffered data to be sent.

Receiving

Wire.requestFrom(address, count)Read "count" bytes from a device at "address". Master mode is used.

Wire.available()Returns the number of bytes available by calling receive.

Wire.read()Receive 1 byte.

Steps to send data to Labview vibration and temperature platform using IoT long-range wireless vibration, temperature sensor and long-range wireless mesh modem with USB interface:

First, we need a Labview utility application which is ncd.io Wireless Vibration and Temperature Sensor.exe file on which data can be viewed.

This Labview software will work with ncd.io wireless Vibration Temperature sensor only

To use this UI, you will need to install following drivers Install run time engine from here 64bit

32 bit

Install NI Visa Driver

Install LabVIEW Run-Time Engine and NI-Serial Runtime

Getting started guide for this product.

Uploading the code to ESP32 using Arduino IDE:

Download and include the PubSubClient Library and Wire.h Library.

You must assign your unique Ubidots TOKEN, MQTTCLIENTNAME, SSID (WiFi Name) and Password of the available network.

Compile and upload the Ncd__vibration_and_temperature.ino code.

To verify the connectivity of the device and the data sent, open the serial monitor. If no response is seen, try unplugging your ESP32 and then plugging it again. Make sure the baud rate of the Serial monitor is set to the same one specified in your code 115200.

Serial Monitor Output:

Data on serial monitor of Arduino IDE.

Making the Ubidot Work:

Create the account on Ubidot.

Go to my profile and note down the token key which is a unique key for every account and paste it to your ESP32 code before uploading.

Add a new device to your Ubidot dashboard name ESP32.

Now you should see the published data in your Ubidots account, inside the device called "ESP32".

Inside the device create a new variable name sensor in which your temperature reading will be shown.

Now you are able to view the Temperature and other sensors data which was previously viewed in the serial monitor. This happened because the value of different sensor readings is passed as a string and store in a variable and publish to a variable inside device esp32.

Create a dashboard in ubidots.

Go to data select dashboard and inside dashboard create different widgets and add a new widget to your dashboard screen.

OUTPUT

Now as the temperature/vibration increases and decreases new data available inside the various variable.

Creating Events in Ubidots

1) Select Events (from the Data dropdown).

2) To create a new event, click the yellow plus icon in the upper right corner of the screen.

Types of Events: Ubidots support already integrated events to allow you to send Events, Alerts, and Notifications to those who need to know when they need to know. Ubidots' prebuilt integrations include:

Email notifications

SMS notifications

Webhook events - learn more

Telegram notifications

Slack notifications - learn more

Voice Call notifications - learn more

Back to Normal notification - learn more

Geofence notifications - learn more

3) Then choose a device and associating variable that indicates the devices' "values".

4) Now select a threshold value for your event to trigger and compare it to device values and also select time to trigger your event.

5) Establish and configure which actions are to be executed and the message to the receiver: Send SMS, Email, Webhooks, Telegrams, Phone Calls, SLACK, and webhooks to those who need to know.

6) Configure the Event notice.

7) Determine the activity window the events may/may not be executed.

8) Confirm your Events.

The output of Event in Your Mail:

Export Your Ubidots Data to Google Sheets:

In this, we can extract the data stored in the Ubidots cloud for further analysis. The possibilities are enormous; for instance, you could create an automatic report generator and send them to your customers every week.

Another application would be device provisioning; if you have thousands of devices to deploy, and their information is in a Google Sheet, you could create a script to read the sheet and create a Ubidots data source for every line on the file. Steps to do this-

Create a Google Sheet and add two sheets to it with these names:

 Variables

Values

From your Google Sheet, click on "Tools" then "Script Editor...", then "Blank Project".

Open the Script Editor.

Add the code below (in the code section) to the script Script.

Done! now open your Google Sheet again and you'll see a new menu to trigger the functions.

Result:

SWORDSOFT LAYOUT SERIAL NUMBER HOW TO

SWORDSOFT LAYOUT SERIAL NUMBER CODE

However, if you have peripherals connected to those pins, you may have trouble trying to upload new code, flashing the ESP32 with new firmware, or resetting the board. More information on the ESP32 Boot Mode Selection can be found here. The board puts the pins in the right state for flashing or boot mode. On most development boards with built-in USB/Serial, you don’t need to worry about the state of these pins. These are used to put the ESP32 into bootloader or flashing mode. The ESP32 chip has the following strapping pins:

SWORDSOFT LAYOUT SERIAL NUMBER HOW TO

Learn how to use interrupts with the ESP32: Learn more about SPI communication protocol with the ESP32 using Arduino IDE: ESP32 SPI Communication: Set Pins, Multiple SPI Bus Interfaces, and Peripherals (Arduino IDE) InterruptsĪll GPIOs can be configured as interrupts. Learn more about I2C communication protocol with the ESP32 using Arduino IDE: ESP32 I2C Communication (Set Pins, Multiple Bus Interfaces and Peripherals) SPIīy default, the pin mapping for SPI is: SPI If you want to use other pins when using the wire library, you just need to call: Wire.begin(SDA, SCL) When using the ESP32 with the Arduino IDE, the default I2C pins are: The ESP32 has two I2C channels and any pin can be set as SDA or SCL. Learn how to use ESP32 PWM with Arduino IDE: ESP32 PWM with Arduino IDE I2C GPIO where you want to output the signal.To set a PWM signal, you need to define these parameters in the code: All pins that can act as outputs can be used as PWM pins (GPIOs 34 to 39 can’t generate PWM). The ESP32 LED PWM controller has 16 independent channels that can be configured to generate PWM signals with different properties. Learn how to use the RTC GPIOs to wake up the ESP32 from deep sleep: ESP32 Deep Sleep with Arduino IDE and Wake Up Sources PWM The following GPIOs can be used as an external wake up source. These RTC GPIOs can be used to wake up the ESP32 from deep sleep when the Ultra Low Power (ULP) co-processor is running. The GPIOs routed to the RTC low-power subsystem can be used when the ESP32 is in deep sleep. There are 2 x 8 bits DAC channels on the ESP32 to convert digital signals into analog voltage signal outputs. View source Digital to Analog Converter (DAC) You’ll get a behavior similar to the one shown in the following figure. You need to keep that in mind when using the ADC pins. You’ll probably won’t be able to distinguish between 0 and 0.1V, or between 3.2 and 3.3V. The ESP32 ADC pins don’t have a linear behavior.

SWORDSOFT LAYOUT SERIAL NUMBER CODE

You can also set the resolution of your channels on the code and the ADC range. This means that you can get analog readings ranging from 0 to 4095, in which 0 corresponds to 0V and 4095 to 3.3V. The ADC input channels have a 12-bit resolution. So, if you’re using Wi-Fi and you’re having trouble getting the value from an ADC2 GPIO, you may consider using an ADC1 GPIO instead. Note: ADC2 pins cannot be used when Wi-Fi is used. The ESP32 has 18 x 12 bits ADC input channels (while the ESP8266 only has 1x 10 bits ADC). These are the GPIOs that can be used as ADC and respective channels: Learn how to use the touch pins with Arduino IDE: ESP32 Touch Pins with Arduino IDE Analog to Digital Converter (ADC) Those internal touch sensors are connected to these GPIOs: The capacitive touch pins can also be used to wake up the ESP32 from deep sleep. These pins can be easily integrated into capacitive pads and replace mechanical buttons. So they can detect variations induced when touching the GPIOs with a finger. These can sense variations in anything that holds an electrical charge, like the human skin. The ESP32 has 10 internal capacitive touch sensors. So, don’t use these pins in your projects: However, these pins are connected to the integrated SPI flash on the ESP-WROOM-32 chip and are not recommended for other uses. GPIO 6 to GPIO 11 are exposed in some ESP32 development boards. They can’t be used as outputs, so use these pins only as inputs: These pins don’t have internal pull-up or pull-down resistors. GPIOs 34 to 39 are GPIs – input only pins. GPIOĬontinue reading for a more detail and in-depth analysis of the ESP32 GPIOs and its functions. The pins highlighted in red are not recommended to use as inputs or outputs. The ones highlighted in yellow are OK to use, but you need to pay attention because they may have an unexpected behavior mainly at boot. The pins highlighted in green are OK to use. The following table shows what pins are best to use as inputs, outputs and which ones you need to be cautious. Additionally, there are pins with specific features that make them suitable or not for a particular project.

Parte 1: Introduzione

Guida a puntate su ESP8266

Cosa ci fa una guida su un hardware (si ESP8266 è un hardware) che non è Raspberry Pi, su un sito dedicato al Raspberry Pi? Bè, cominciate a leggere, e scoprirete che esistono molti più punti di contatto tra questi due oggetti, di quanto sospettavate. E sopratutto, non esiste (ancora) una documentazione chiara, completa e che parta da zero in italiano su questo oggetto, il che lo rende particolarmente ostico da affrontare per chi è alle prime armi con oggetti del genere. L’innumerevole varietà di versioni hardware e gli svariati firmware differenti, fanno perdere per strada il novellino in una marea di tutorial e guide in inglese, contraddittorie e totalmente differenti tra loro. E allora.. perchè non pensarci noi? Realizzeremo una serie di guide che ci porteranno a scoprire assieme questa piccola scheda, come programmarla, i vari firmware e gli usi pratici.

Ma di cosa stiamo parlando?

L’ ESP8266 si tratta si un SoC (System on Chip) prodotto dalla Cinese Espressif, contiene un microcontrollore, un modulo WiFi con stack TCP-IP completo. Sopratutto, ha un basso costo.

Ok, cosa è un microcontrollore?

Senza divagare troppo nel tecnico, possiamo dire che un microcontrollore (MCU), a differenza di un microprocessore (CPU) è meno raffinato, meno general purpose, più specializzato in un solo compito. Però questo consente di avere più componenti integrate (il processore, la memoria permanente, la memoria volatile e i canali di I/O), il che gli consente di funzionare con pochissimi (a volte nessun) componente esterno, mentre un microprocessore richiede una intera scheda madre e unità esterne, memorie, periferiche. Nei microcontrollori il programma da eseguire viene memorizzato direttamente nella ROM, assieme al firmware. Quindi non è in grado (non necessita) di un sistema operativo, con i relativi vantaggi/svantaggi che questo comporta. Tutto questo li rende molto economici quindi preferiti nelle applicazioni specifiche (calcolatrici, centraline di auto, modem, antifurti, elettrodomestici ecc ecc).

Storia

I microcontrollori esistono di ogni specie e versione, e fino a poco tempo fa non esisteva una configurazione standardizzata, e spesso i maker si creavano da soli la scheda con l’elettronica di contorno utile al loro funzionamento. Questo produceva un hardware diverso per ognuno. Proprio per questo nacque Arduino, che creava una scheda Open Hardware standard con microcontrollore Atmel, e fu un gran successo. Poi nacque l’ESP8266, e il WiFi integrato è stata la sua arma vincente per distinguersi. Vista proprio l’estrema economicità, produttori di terze parti hanno incominciato a commercializzare piccoli moduli che montavano ESP8266, ottenendo subito (verso il 2014) un grande successo presso le comunità dei maker. E’ un SoC pensato per la produzione industriale (piccolo, i pin non hanno un passo standard, sono pensati per il montaggio SMD) quindi per usarlo a livello hobbystico più facilmente, è indispensabile averlo montato su una scheda con elettronica di contorno più o meno completa.

Versioni di ESP8266

Questo ha generato una marea di versioni in commercio differenti, di queste schedine. Le varianti più diffuse sono quelle prodotte da AI-Thinker, nominate ESP-01 , ESP-02, fino a ESP-14, ma ne esistono diverse di altri produttori, più o meno equivalenti. Si differenziano tra loro per le caratteristiche costruttive: il tipo di antenna del WiFi, la certificazione FCC o meno, la quantità di memoria, la presenza o meno di adattatori usb/seriali a bordo, il numero di Pin attivi. I prezzi sono irrisori: se comprate in Cina si va da 1,5 Euro per ESP-01 alle 3 Euro scarse per la scheda di sviluppo più completa con ESP-12E, ma i tempi di consegna sono oltre il mese (più vicino ai 60 giorni); in Italia, fate più o meno il doppio dei prezzi, ma potete comprare da Amazon.

GPIO

Si, l’ESP2866 ha dei pin liberi, programmabili dall’utente finale. un vero e proprio GPIO, e qui cominciano a notarsi le somiglianze con Raspberry Pi. Su questi pin sono disponibili I2C, SPI, UART, diversi pin ingressi/uscite digitali programmabili, e un ingresso analogico con ADC a 10 bit.

Caratteristiche

RISC CPU a 32-bit: Tensilica Xtensa LX106 funzionante a 80 MHz*

4Kb di memoria RAM per le istruzioni e 96Kb di memoria RAM per i dati

stack TCP/IP e la possibilità di collegarsi alle reti wifi b/g/n

supporto per un Flash RAM esterna da 512Kb a 4Mb a seconda della versione, in cui viene memorizzato il programma

16 GPIO (anche se non su tutti i moduli sono utilizzabili tutti e 16)

UART / I2C / I2S/ SPI / 1 modulo ADC a 10bit

* su alcune versioni, overcloccate, la CPU può funzionare a 160Mhz e la Flash RAM a 80Mhz (invece di 40)

Confusi? Non è ancora finita: per ogni versione Hardware, è possibile montare svariate tipologie di firmware completamente differenti, che cambiano in toto il modo in cui viene gestita la scheda e il linguaggio che useremo per comunicare con essa o per programmarla:

Firmware

Infatti, oltre al firmware di fabbrica di Espressif che utilizza i comandi AT per comunicare con il chip, sono stati sviluppati altri firmware alternativi che permettono di sfruttare molto meglio le potenzialità di questo piccolo gioiello tecnologico: Eccone alcuni, tra quelli Open Source:

NodeMCU: firmware basato sul linguaggio Lua

Arduino: firmware basato su C++. permette di programmare l’ESP8266 e la componente WiFi come fossero un Arduino. Disponibile su GitHub.

MicroPython: un port di MicroPython (una versione di Python per microcontrollori).

ESP8266 BASIC: un Basic Open Source adattato per l’IoT (Internet of Things).

Zbasic for ESP8266: Un sottoinsieme del diffuso Visual basic 6 di Microsoft, adattato a linguaggio per i microcontrollori della serie ZX e per l’ESP8266.

Mongoose Firmware: un firmware open source con servizio cloud gratuito

Open RTOS

ok, ma alla fine, che ci faccio?

L’ESP8266 può essere utilizzato in almeno in due modalità principali: come scheda a sé stante, o come accessorio per il nostro Raspberry. Vediamo prima quest’ultima: può essere configurato per fare da bridge USB/seriale – Wifi, per trasformare le connessioni seriali o USB in connessioni Wifi senza fili in modo da far acquisire la funzionalità wireless a qualche dispositivo che già usate con Raspberry Pi (controller, centraline varie, apparecchiature industriali..). Oppure è perfetto per raccogliere i dati di diversi sensori e trasferirli via Wifi al Raspberry, o viceversa fare da Hub wireless per diversi attuatori (relè, motori..). Uso “stand-alone”: avete sviluppato e ottimizato il vostro progetto di physical computing con Raspberry? Bene, perchè sprecare così il Raspberry Pi? Probabilmente, nella maggior parte dei casi, quel compito lo può svolgere anche ESP8266, basterà adattare il vostro programma, e con Python potrebbe essere anche meno complicato che portare pace e armonia nel mondo. Implementazioni quali quelle che leggono sensori, comandano relè e LED, ma anche che pilotano display o gestiscono interfacce web, possono tranquillamente essere portate su ESP2866, con evidente risparmio di denaro e con una realizzazione meno delicata e più adatta all’ uso embedded (non c’è la SD, il programma andrà a risiedere nella ROM) e più compatta. Le dimensioni assai contenute e la capacità di connettersi via WiFi, rendono questa scheda perfetta per le applicazioni di domotica: facile da integrare negli impianti esistenti essendo poco ingombrante e non richiedendo cablaggi per la rete ethernet cablata. Per gli stessi motivi, è perfetta anche per le applicazioni nel campo dell’IoT (Internet of Things). Inoltre, è possibile comandarla via smartphone con apposite app.

Come vedete, la carne al fuoco è davvero tanta.

Fermi! Non correte subito a comprarne un esemplare, invogliati dal prezzo allettante! Nella prossima puntata, vedremo le versioni hardware più diffuse, come farle funzionare, e qualche suggerimento su quale modello scegliere per cominciare a sperimentare subito questo nuovo mondo. Seguiteci!

Embedded systems are computer systems inside a larger system, with a specific function that it is designed for. It is composed of both hardware and software. They integrate different mechanical, chemical and electrical parts. These kinds of systems can be classified into three different types: small scale embedded systems, medium scale embedded systems, and sophisticated embedded systems. 1) Small scale embedded systems: These usually use 8 bit or 16 bit microcontrollers, and have minimum hardware and software. They are so small and require little power they may be powered by a battery. 2) Medium scale embedded systems: They use either one or a few 16 bit or 32 bit microcontrollers, and hardware and software is more complex as compared to small scale embedded systems. 3) Sophisticated embedded systems: The most complex of the three classifications mentioned. Examples of embedded systems include numerous products such as microwave ovens, washing machine, printers, automobiles, cameras, etc. @pantechelearning #pantechelearning Any queries regarding major and mini projects contact 📞 us: WhatsApp us:+91 8925533483/82 Website:https://ift.tt/3qgQVo0. . .... . . . . . . . . #pantechelearning #pantechammerpet #embedded #arduino #raspberrypi #iot #engineering #robotics #electronics #arduinouno #technology #arduinoproject #embeddedsystems #esp #programming #electronicengineering #diyelectronics #microcontroller #coding #pcb #arduinomega #atmega #pcbdesign #arduinoprojects #sensors #electronicsprojects #electricalengineering #electronicslovers #automation https://instagr.am/p/CPADraxFfI5/
