YI Cam Remote Access: Your Guide to Self-Hosted Surveillance

Want to have complete control over your YI Cam and go beyond its default cloud? For more privacy and customization, many users prefer YI Cam Remote Access, rather than using the manufacturer's cloud. Therefore, this post explores how to accomplish this sophisticated configuration, assisting you in navigating the frequently challenging process of self-hosting your camera's feed. Walk through this post to learn more details! 

Understanding the YI Cam Remote Access

Generally, you need to install a custom firewall on your device if you want to access the YI camera remotely and connect it to your server. Additionally, it allows leveraging the benefits of the RTSP (real-time streaming protocol) streaming as well as FTP access.  Moreover, it eliminates the need for third-party platforms and for configuring cameras to the self-hosted servers.

However, it acts as a “Network Remote Controller,” especially for the multimedia servers. It allows users to control media playback remotely. But it does not deliver audio or video streams continuously; instead, it communicates with the servers streaming the multimedia content. Hence, for the YI Cam Remote Access, users must connect their security cameras to the server through RTSP.

How to Connect Camera To Server for YI Remote Access?

Moreover, enabling the YI Cam Remote Access opens up several possibilities and advanced functionalities. So, let’s begin with the essential steps to Connect Camera To Server for managing and monitoring your YI camera remotely. 

Initially, confirm your YI Cam supports the RTSP or streaming compatibility, as some models may require custom firmware.

Subsequently, set up your chosen server device, such as a computer, NAS, or Raspberry Pi, with a suitable operating system.

Next, install essential software like Blue Iris, MotionEye, FFmpeg, or Home Assistant to manage the video feed.

Finally, configure secure remote access using methods such as port forwarding, VPN, or Dynamic DNS for external viewing.

Now, you can view, configure, and control your YI camera remotely.

Bottom Line

In conclusion, YI Cam Remote Access empowers you with full control over your camera's feed through self-hosting, prioritizing privacy & customization. Additionally, this advanced setup typically requires RTSP compatibility, a dedicated server, and management software. With secure remote access methods such as VPN or port forwarding, you can ensure seamless monitoring from anywhere.

Hopefully by March, we will be living in London, near to a lovely queer community. But we also find myself during this current social isolation we suffer, exiled from our tools, we miss taking on projects. This needs to change. Unfortunately said tools are currently packed up, awaiting out move.

So, after we have migrated from this dreary town, we will setup our little "lab" again and intend to work on various projects, including:

- A Raspberry Pi Compute Module 4 powered Linux phone with 4G connectivity (initially)

- A Steampunk meets Atompunk desk, based on a nuclear reactor console

- Setting up Home Assistant powered smart tech in the new home, from lights to temperature control, etc

Have any ideas? Let me know! My specialism is Python, though I'm always up for learning something new. Challenges inspire me.

Applied AI - Integrating AI With a Roomba

AKA. What have I been doing for the past month and a half

Everyone loves Roombas. Cats. People. Cat-people. There have been a number of Roomba hacks posted online over the years, but an often overlooked point is how very easy it is to use Roombas for cheap applied robotics projects.

Continuing on from a project done for academic purposes, today's showcase is a work in progress for a real-world application of Speech-to-text, actionable, transformer based AI models. MARVINA (Multimodal Artificial Robotics Verification Intelligence Network Application) is being applied, in this case, to this Roomba, modified with a Raspberry Pi 3B, a 1080p camera, and a combined mic and speaker system.

The hardware specifics have been a fun challenge over the past couple of months, especially relating to the construction of the 3D mounts for the camera and audio input/output system.

Roomba models are particularly well suited to tinkering - the serial connector allows the interface of external hardware - with iRobot (the provider company) having a full manual for commands that can be sent to the Roomba itself. It can even play entire songs! (Highly recommend)

Scope:

Current:

The aim of this project is to, initially, replicate the verbal command system which powers the current virtual environment based system.

This has been achieved with the custom MARVINA AI system, which is interfaced with both the Pocket Sphinx Speech-To-Text (SpeechRecognition · PyPI) and Piper-TTS Text-To-Speech (GitHub - rhasspy/piper: A fast, local neural text to speech system) AI systems. This gives the AI the ability to do one of 8 commands, give verbal output, and use a limited-training version of the emotional-empathy system.

This has mostly been achieved. Now that I know it's functional I can now justify spending money on a better microphone/speaker system so I don't have to shout at the poor thing!

The latency time for the Raspberry PI 3B for each output is a very spritely 75ms! This allows for plenty of time between the current AI input "framerate" of 500ms.

Future - Software:

Subsequent testing will imbue the Roomba with a greater sense of abstracted "emotion" - the AI having a ground set of emotional state variables which decide how it, and the interacting person, are "feeling" at any given point in time.

This, ideally, is to give the AI system a sense of motivation. The AI is essentially being given separate drives for social connection, curiosity and other emotional states. The programming will be designed to optimise for those, while the emotional model will regulate this on a seperate, biologically based, system of under and over stimulation.

In other words, a motivational system that incentivises only up to a point.

The current system does have a system implemented, but this only has very limited testing data. One of the key parts of this project's success will be to generatively create a training data set which will allow for high-quality interactions.

The future of MARVINA-R will be relating to expanding the abstracted equivalent of "Theory-of-Mind". - In other words, having MARVINA-R "imagine" a future which could exist in order to consider it's choices, and what actions it wishes to take.

This system is based, in part, upon the Dyna-lang model created by Lin et al. 2023 at UC Berkley ([2308.01399] Learning to Model the World with Language (arxiv.org)) but with a key difference - MARVINA-R will be running with two neural networks - one based on short-term memory and the second based on long-term memory. Decisions will be made based on which is most appropriate, and on how similar the current input data is to the generated world-model of each model.

Once at rest, MARVINA-R will effectively "sleep", essentially keeping the most important memories, and consolidating them into the long-term network if they lead to better outcomes.

This will allow the system to be tailored beyond its current limitations - where it can be designed to be motivated by multiple emotional "pulls" for its attention.

This does, however, also increase the number of AI outputs required per action (by a magnitude of about 10 to 100) so this will need to be carefully considered in terms of the software and hardware requirements.

Results So Far:

Here is the current prototyping setup for MARVINA-R. As of a couple of weeks ago, I was able to run the entire RaspberryPi and applied hardware setup and successfully interface with the robot with the components disconnected.

I'll upload a video of the final stage of initial testing in the near future - it's great fun!

The main issues really do come down to hardware limitations. The microphone is a cheap ~$6 thing from Amazon and requires you to shout at the poor robot to get it to do anything! The second limitation currently comes from outputting the text-to-speech, which does have a time lag from speaking to output of around 4 seconds. Not terrible, but also can be improved.

To my mind, the proof of concept has been created - this is possible. Now I can justify further time, and investment, for better parts and for more software engineering!

Setting up a Raspberry Pi is always an adventure, and our latest project has been no exception! We've been diving deep into the world of network configuration, and after a bit of head-scratching (and a few "aha!" moments), we've made some significant progress in understanding how to get our Pi to share its internet connection.

Initially, like many, we fell into a common trap. Our goal was to share the internet connection from our Raspberry Pi, and our first thought was to assign a static IP address to wlan0 – the wireless interface. The logic seemed sound: wlan0 is how the Pi connects to the internet (via a hotspot, in our case), so surely that's where the magic needed to happen, right?

Not quite!

After some experimentation and a healthy dose of troubleshooting, we realized a crucial distinction. While wlan0 receives the internet connection, it's not the ideal interface for sharing it in the way we envisioned. Think of it this way: wlan0 is like the person receiving a package at the door. They've got the package, but they're not the ones distributing it to everyone else in the house.

This led us to eth0 – the trusty wired Ethernet port. And that's where the real breakthrough happened! We had a lightbulb moment: eth0 is perfectly suited for sharing the connection.

Here's why eth0 is our new best friend for internet sharing:

* Dedicated Connection: eth0 allows for a direct, dedicated connection to another device, like a router or even another computer. This is ideal for creating a stable and reliable shared network.

* Logical Separation: By using eth0 to share, we can keep the wlan0 interface focused on its primary job: connecting to the internet. This simplifies the network topology and makes it easier to manage.

* Foundation for a Robust Setup: With eth0 as our sharing interface, we can now configure it to act as a DHCP server, enable IP forwarding, and set up Network Address Translation (NAT). These are the essential ingredients for turning our Raspberry Pi into a powerful internet gateway.

So, what's the plan moving forward?

Our focus has now shifted to configuring eth0. We'll be looking at:

* Assigning a static IP address to eth0: This will be the gateway for any devices connected to it.

* Enabling IP forwarding: This is the key to telling the Pi to route traffic between our wlan0 internet source and our eth0 shared network.

* Setting up a DHCP server (like dnsmasq) on eth0: This will allow devices connected to eth0 to automatically get an IP address from our Pi.

* Configuring iptables for NAT: This crucial step will ensure that devices on our eth0 network can access the internet through our wlan0 connection.

This project has been a fantastic learning experience, highlighting the importance of understanding the fundamental roles of different network interfaces. We're excited to get eth0 fully configured and unlock the full potential of our Raspberry Pi as an internet sharing hub.

Stay tuned for more updates as we continue to build out this network!

Chatgpt computer communication design

Designing a computer circuit where two computers communicate with each other and "teach themselves" using an Arduino board involves a combination of hardware setup and software programming. Here’s a general guide to get you started:

1. Basic Concept

Two Computers (PCs or Microcontrollers): These are the two devices that will communicate and learn from each other. Each will run a program for self-learning.

Arduino Board: The Arduino will facilitate the communication between the two computers and control the process. It could also be part of the system performing calculations or simulations.

Communication Protocol: The two computers will need to communicate with each other. For simplicity, we can use serial communication (UART) or I2C with the Arduino acting as the intermediary.

2. Hardware Components

Arduino Board (e.g., Arduino Uno, Nano, or Mega)

Two Computers (PCs or other microcontrollers, like Raspberry Pi or other Arduino boards)

Communication Module: If you are using something like a Raspberry Pi or another microcontroller, you might need USB-to-Serial adapters or Bluetooth/Wi-Fi modules (e.g., ESP8266/ESP32, HC-05).

Power Supply: Proper power sources for the Arduino and computers.

Cables: USB, serial cables, or jumper wires for communication.

3. Circuit Design

Here is a high-level overview of the connections between the Arduino and the two computers.

Arduino and PC1 (Computer 1):

Connect the Arduino to PC1 via USB or UART communication pins (TX/RX pins if using serial).

Arduino and PC2 (Computer 2):

If you are using a second microcontroller (like another Arduino or a Raspberry Pi), connect them to the Arduino board using a communication protocol (e.g., I2C or UART).

The two computers could either communicate directly over a network (like Ethernet or Wi-Fi) or through serial communication.

For this example, let’s assume you are using UART for communication between the Arduino and both computers. You can use the TX/RX pins on the Arduino and connect them to the USB-to-Serial adapters connected to each computer.

4. Software Design

The software should allow the computers to "teach themselves," which likely means implementing some form of machine learning or pattern recognition. For simplicity, let’s outline how you could set up communication, with the learning part handled on the computers.

Arduino Code: The Arduino will act as the middleman for the communication. It will receive data from one computer, send it to the other, and also handle basic processing or simulation. It can be programmed to send responses or instructions back to the computers.

// Simple Arduino code for UART communication void setup() { Serial.begin(9600); // Start the serial communication at 9600 baud } void loop() { if (Serial.available()) { char incomingByte = Serial.read(); // Read incoming byte Serial.print("Received: "); Serial.println(incomingByte); // Send back the received byte } }

Computer 1 and Computer 2 Code: Each computer should run a program that will send data to the Arduino and receive responses. This could be a simple Python script or C++ program for serial communication.

Example Python Script: Here’s a basic Python script that can run on each computer. This script will send data to the Arduino and read the response back.import serial import time # Open serial port (make sure to change COM port for your system) ser = serial.Serial('COM3', 9600) # Change COM port as needed time.sleep(2) # Wait for the serial connection to initialize # Send data to Arduino ser.write(b'Hello Arduino!\n') # Read response while True: if ser.in_waiting > 0: response = ser.readline().decode('utf-8').strip() print(f"Arduino says: {response}") break ser.close()

This Python script could run on Computer 1, while a similar script runs on Computer 2. Both will send messages to the Arduino and receive feedback.

5. Self-Learning Simulation

To simulate the "self-teaching" aspect, each computer can use machine learning algorithms. You could start with something simple like linear regression or a decision tree. The computers could send random data points to each other and exchange feedback on whether the predictions made by each other are correct.

Computer 1 could generate a random dataset and send it to Computer 2.

Computer 2 processes the data, makes predictions, and sends the feedback back.

Computer 1 uses this feedback to adjust its learning algorithm (e.g., adjust weights in a simple linear regression model).

Example of a Simple Learning Process: Each computer could adjust its internal model based on the received feedback, similar to how a neural network or other machine learning models learn. The Arduino could be involved in simple processing tasks or sending acknowledgment signals when certain thresholds are reached (e.g., "success" or "failure").

6. Scaling Up

If you want to scale up the project to involve more complex learning or higher levels of interaction, you could use a more advanced platform such as a Raspberry Pi or ESP32/ESP8266 for networking and faster processing, where each computer uses a machine learning library (like TensorFlow Lite or scikit-learn).

7. Final Setup

Computer 1 and Computer 2 run machine learning algorithms that adjust based on feedback.

Arduino manages data flow between the computers and possibly performs basic learning tasks like adjusting variables or sending commands.

The entire system simulates a network where two computers are learning from each other.

This is a high-level overview, and there are many ways to implement it depending on the complexity of the communication and learning algorithm you want to achieve. Would you like to dive deeper into any specific area or need more detailed code for the project?

Creating two PCs from scratch using Arduino boards is an interesting challenge, but it's important to note that a full-fledged personal computer involves much more complexity than an Arduino is capable of. However, you can certainly simulate basic "PC-like" behavior using Arduino boards, where each "PC" would be a microcontroller (Arduino) with some level of functionality, communication, and processing.

High-Level Concept

Each Arduino board would act as a basic computing unit (like a simplified "PC"), running simple programs, processing input, and communicating with each other. While these "PCs" won't have the advanced features of a real computer (like an OS, GUI, or complex processing power), they can serve as learning devices or communication nodes in a network.

To make two PCs communicate with each other using an Arduino board, the Arduino acts as an intermediary. The Arduino will handle the communication between the two PCs, either via a serial connection (UART), I2C, or wireless communication (e.g., Bluetooth/Wi-Fi). Below is a guide on how to set up such a system:

1. Hardware Setup

Here, I'll describe a setup where two PCs communicate via an Arduino board using serial communication (UART). The Arduino will act as a mediator, forwarding messages between the two computers.

Components Needed:

Arduino board (e.g., Arduino Uno, Nano, Mega)

2 PCs (PC1 and PC2)

USB-to-Serial adapters (if using UART)

Jumper wires (if using direct communication between Arduino and PC)

Connections:

PC1 <-> Arduino: The first PC will communicate with the Arduino using its USB port (acting as a serial port).

PC2 <-> Arduino: The second PC will communicate via another USB-to-Serial adapter or possibly the second USB port of the Arduino (if the Arduino model supports multiple serial connections, e.g., Mega).

In simpler terms:

Arduino will be connected via USB to PC1.

PC2 will be connected to Arduino's serial pins (TX/RX) or using a USB-to-Serial adapter.

2. Arduino Code

The Arduino will need to read from one serial port (PC1) and forward the data to another serial port (PC2) and vice versa. The following is a simple Arduino sketch for this task.// Arduino code for mediating between two PCs void setup() { // Start serial communication with both computers Serial.begin(9600); // For communication with PC1 Serial1.begin(9600); // For communication with PC2 (if using Arduino Mega or another board with multiple serial ports) } void loop() { // Check if data is available from PC1 (connected to Serial) if (Serial.available() > 0) { char dataFromPC1 = Serial.read(); // Read data from PC1 Serial1.write(dataFromPC1); // Send data to PC2 (connected to Serial1) } // Check if data is available from PC2 (connected to Serial1) if (Serial1.available() > 0) { char dataFromPC2 = Serial1.read(); // Read data from PC2 Serial.write(dataFromPC2); // Send data to PC1 (connected to Serial) } }

Explanation of the Code:

Serial.begin(9600): Initializes communication with PC1.

Serial1.begin(9600): Initializes communication with PC2. (Note: Only available on boards with multiple UARTs like Arduino Mega, if using an Arduino Uno, you’ll need a USB-to-Serial adapter for PC2).

Serial.read(): Reads data from one serial port.

Serial.write(): Sends data to the other serial port.

3. Software on the PCs

On each of the two PCs, you will run a program that communicates with the Arduino via a serial connection. You can use Python to interface with the Arduino. Here’s a simple Python example that reads data from the Arduino and sends data back.

Python Code for PC1:

import serial import time # Connect to Arduino via serial port (Adjust the port name as needed) ser = serial.Serial('COM3', 9600) # Replace 'COM3' with your Arduino's port time.sleep(2) # Wait for the serial connection to establish # Send data to Arduino (which will forward to PC2) ser.write(b'Hello from PC1!\n') # Read data from Arduino (which is coming from PC2) while True: if ser.in_waiting > 0: response = ser.readline().decode('utf-8').strip() print(f"Received from PC2: {response}") break ser.close()

Python Code for PC2:

import serial import time # Connect to Arduino via serial port (Adjust the port name as needed) ser = serial.Serial('COM4', 9600) # Replace 'COM4' with your Arduino's port time.sleep(2) # Wait for the serial connection to establish # Read data from Arduino (which is coming from PC1) while True: if ser.in_waiting > 0: message = ser.readline().decode('utf-8').strip() print(f"Received from PC1: {message}") # Send data back to Arduino (which will forward to PC1) ser.write(b'Hello from PC2!\n') break ser.close()

4. Explanation of the PC Software:

Python serial library: Used to open a serial connection to the Arduino.

ser.write(): Sends data from PC1 or PC2 to the Arduino.

ser.readline(): Reads incoming data from the Arduino, which is forwarded from the other PC.

Time Delays: time.sleep(2) ensures that the serial connection is established before communication begins.

5. Communication Flow

PC1 sends a message (e.g., "Hello from PC1") to the Arduino.

The Arduino forwards the message to PC2.

PC2 receives the message, processes it, and sends a response back to the Arduino (e.g., "Hello from PC2").

The Arduino forwards the message back to PC1.

6. Adjusting for More Complex Setups

If you are using an Arduino Uno (which has only one serial port), you’ll need an additional USB-to-Serial adapter to handle communication with both PCs. Alternatively, you can use an Arduino Mega, which has multiple serial ports (like Serial, Serial1, Serial2, etc.).

For the Arduino Mega, you can use Serial for PC1 and Serial1 for PC2, as shown in the code above.

For PC2, you might need a USB-to-Serial adapter if you're not using an Arduino Mega.

7. Next Steps

To make the setup more advanced, you can:

Add error handling and retry mechanisms for more robust communication.

Implement data processing algorithms to simulate machine learning (e.g., a simple model for each PC that "learns" from the data it receives).

Use wireless communication like Bluetooth or Wi-Fi if you don't want to rely on USB connections.

Would you like to explore how to expand this further or add more complexity to the system? Let me know!

Here’s how you might approach creating two Arduino-based "PCs" from scratch:

1. Basic Requirements and Constraints

You’re working with Arduino boards, which are microcontrollers with limited processing power, memory, and storage compared to a real PC. The Arduino can run basic programs, perform calculations, and communicate with other devices, but it cannot run complex software like a PC.

To simulate PCs, you'll need:

Arduino microcontroller boards (e.g., Arduino Uno, Nano, Mega, etc.)

Inputs/outputs (e.g., buttons, LEDs, displays)

Communication method between the two Arduinos (e.g., UART serial, I2C, or even wireless)

Storage (limited, but can use EEPROM or SD card modules)

Basic display (e.g., an LCD or LED screen for output)

2. Building the Two "PCs" with Arduino

Each Arduino board will act as one "PC." Here’s how you can conceptualize the setup:

Arduino 1 (PC1): Will handle user input and perform computations.

Arduino 2 (PC2): Will also handle user input and perform computations. It will communicate with PC1 to share or exchange data.

The communication between the two PCs can be done using serial communication (UART) or I2C.

3. Basic Hardware Setup for Each PC

Each "PC" could have:

Buttons or switches to simulate input (e.g., user input or commands).

LCD or 7-segment display for output (or use an LED to indicate activity).

Communication interface to talk to the other PC (e.g., UART or I2C).

SD card or EEPROM to simulate storage.

Components Needed:

2 Arduino boards (e.g., Arduino Uno or Nano)

1 LCD display (16x2 or 20x4 for basic text output)

2 push buttons (to simulate input)

2 LEDs (to indicate some activity or status)

2 USB-to-Serial adapters (if using UART communication between PCs)

1 I2C or UART communication method

1 SD card module (optional for storage simulation)

4. Software Design for the "PCs"

Each Arduino PC will need a program to read inputs, perform some basic computation, and send/receive data to/from the other PC. Here’s a simple breakdown of the software for each Arduino:

Arduino PC1 (PC1 Sketch)

This sketch allows PC1 to process input (button presses), perform simple calculations, and send/receive data from PC2.#include <Wire.h> // For I2C communication (if using I2C) #include <LiquidCrystal_I2C.h> // For LCD display // Initialize the LCD (change pin numbers according to your setup) LiquidCrystal_I2C lcd(0x27, 16, 2); // Input and output pins int buttonPin = 7; // Pin for button input int ledPin = 13; // Pin for LED output void setup() { // Start communication Wire.begin(); // Start I2C communication if using I2C lcd.begin(16, 2); pinMode(buttonPin, INPUT); pinMode(ledPin, OUTPUT); lcd.print("PC1: Ready"); delay(2000); // Wait for 2 seconds } void loop() { int buttonState = digitalRead(buttonPin); // Read button state if (buttonState == HIGH) { // If button is pressed digitalWrite(ledPin, HIGH); // Turn on LED lcd.clear(); lcd.print("Button Pressed"); // Send data to PC2 (via I2C or serial) Wire.beginTransmission(8); // 8 is the I2C address of PC2 Wire.write("PC1: Button Pressed"); Wire.endTransmission(); } else { digitalWrite(ledPin, LOW); // Turn off LED } delay(100); // Small delay to avoid bouncing }

Arduino PC2 (PC2 Sketch)

This sketch for PC2 will receive data from PC1 and display it on the LCD, simulating output.#include <Wire.h> // For I2C communication (if using I2C) #include <LiquidCrystal_I2C.h> // For LCD display LiquidCrystal_I2C lcd(0x27, 16, 2); // LCD setup void setup() { Wire.begin(8); // Set PC2's I2C address to 8 Wire.onReceive(receiveEvent); // Define the event handler for receiving data lcd.begin(16, 2); // Start the LCD display lcd.print("PC2: Ready"); } void loop() { // Main loop does nothing, waiting for incoming data } void receiveEvent(int bytes) { String message = ""; // Initialize an empty string for the message while (Wire.available()) { message += (char)Wire.read(); // Read each byte and convert to character } // Display the received message on LCD lcd.clear(); lcd.print("PC2: "); lcd.print(message); // Print received message on LCD }

5. How They Communicate:

I2C Communication: In this setup, PC1 sends a message to PC2 using I2C. This allows you to connect the two Arduinos with just two wires (SDA, SCL) and share data.

Serial Communication (UART): Alternatively, if you're using UART (Serial) communication, PC1 sends data to PC2 via the Arduino’s TX/RX pins and vice versa.

6. Adding Storage (Optional)

To simulate storage, you can attach an SD card module to the Arduino. The Arduino can read/write simple text files or store computational results on the SD card.

Example of using an SD card module on PC1:#include <SPI.h> #include <SD.h> File myFile; void setup() { Serial.begin(9600); if (!SD.begin(4)) { Serial.println("SD card initialization failed!"); return; } myFile = SD.open("log.txt", FILE_WRITE); if (myFile) { myFile.println("PC1: Data Log"); myFile.close(); } else { Serial.println("Error opening log.txt"); } } void loop() { // Example of logging data continuously myFile = SD.open("log.txt", FILE_WRITE); if (myFile) { myFile.println("New Data Recorded"); myFile.close(); } delay(1000); // Wait for 1 second }

7. Expanding the "PCs"

You can add more features to each Arduino "PC," such as:

User input: Keyboard or mouse emulation.

Network Communication: Use Wi-Fi or Ethernet modules (like ESP8266 or Ethernet shield) to allow the two PCs to communicate over a network.

Processing: Implement simple algorithms or calculations on each Arduino to make them more like basic computers.

8. Limitations

Remember that an Arduino board is not a real PC, and it has significant limitations:

Limited processing power and memory.

No operating system or advanced software.

Minimal input/output capabilities.

But it is still a great way to learn about the basics of computer-like behavior, communication, and microcontroller programming.

Conclusion

While building a full-fledged PC using Arduino isn’t feasible, you can create two basic "PC-like" systems by using Arduino boards to simulate basic functionality such as processing, input/output, communication, and storage. This setup is a great way to learn about how computers work at a fundamental level, as well as how data is shared and processed between multiple devices.
