6-channel speaker selector

At the beginning of 2018, we developed the first version of the 6-channel speaker selector using PIC16F88 MCU and ULN2803 Darlington transistor array. In this new design, we redesign it with low-cost MCU and Darlington transistor arrays. This design also provides the same functionality as the 6-channel speaker selector switch we designed earlier.

This new speaker selector uses STC15W201 MCU. This MCU is a low-cost 8051 MCU designed by STC micro. At the time of this writing, the STC15W201 can obtain for less than US$ 0.8. To drive the seven segments and to control the relays, this design uses the popular 74HC595 8-bit shift register ICs.

To select each speaker channel, we use pair of 12V DPDT relays. These relays interface to 74HC595 through a ULN2001D 3-channel Darlington transistor array IC. This 3-channel Darlington driver IC is functionally equivalent to the famous 8-channel ULN2003 IC. This ULN2001D version is an 8-pin IC and is available in both DIP-8 and SOP-8 packages. 

This new board is designed to work with a 12V DC power supply and in our prototype build, we use a 12V/5A SMPS unit to power the whole system.

To get the optimal results with this circuit, use an Omron G2R-2-12DC or an equivalent type of relay with a coil current lower than 100mA. 

The firmware of the STC15W201S is developed using SDCC. To flash the MCU, we use stcgal. Thanks to the built-in bootloader, we can program this MCU using a generally available 5V USB to UART module/dongle. 

The complete build process of the speaker selector is shown in the video below:

The functionality of the firmware is almost identical to the old PIC16F88 firmware. After powering up the system, the active speaker channel is displayed on the seven-segment display. To switch to a different speaker channel, press the button repeatedly with short intervals. 

To mute or disconnect the current speaker channel, press and hold the same button for more than 3 seconds. 

As described above, all functions of this circuit can be the control using a single push switch.

The PCBWay sponsored this project. PCBWay offers high-quality PCB manufacturing and assembling services. Also, they offer CNC and 3D printing services. The Speaker selector PCB is available to order from PCBWay. Check out the PCBWay website for its manufacturing capabilities and pricing.

This project is an open-source hardware project. All its design files, schematics, and firmware source codes are available at Github.com. 

The PCB design, schematic, and other design files of this project are covered with a CERN-OHL-W 2.0 license. Firmware source code is released under the terms of the MIT license.

In fact, you can even stack multiple Motor HATs, up to 32 of them, for controlling up to 64 stepper motors or 128 DC motors (or a mix of the two) - just remember to purchase and solder in a stacking header instead of the one we include. Only two pins (SDA & SCL) are required to drive the multiple motors, and since it's I2C you can also connect any other I2C devices or HATs to the same pins. This chip handles all the motor and speed controls over I2C.

Small servo motor arduino driver#

Since the Raspberry Pi does not have a lot of PWM pins, we use a fully-dedicated PWM driver chip onboard to both control motor direction and speed. Raspberry Pi and motors are not included. This Raspberry Pi add-on is perfect for any motion project as it can drive up to 4 DC or 2 Stepper motors with full PWM speed control. Let your robotic dreams come true with the new DC Stepper Motor HAT from Adafruit.

They provide a nice visual when stepping. The board has four LEDs that show activity on the four control input lines (to indicate stepping state). Four out of seven pairs are used on this board. The ULN2003 is one of the most common motor driver ICs, consisting of an array of 7 Darlington transistor pairs, each pair is capable of driving loads of up to 500mA and 50V. The power consumption of the motor is around 240mA. In addition, the motor has a 1/64 reduction gear set. That means there are 32 steps per revolution (360°/11.25° = 32). The 28BYJ-48 motor runs in full step mode, each step corresponds to a rotation of 11.25°. The maximum speed for a 28byj-48 stepper motor is roughly 10-15 rpm at 5 V.

Basic Electronics Components

Electronic components are fundamental discrete gadgets in any electronic framework to use in electronics in any case extraordinary related fields. These components are fundamental components that are utilized to plan electrical and electronic circuits. These components have at least two terminals which are utilized to interface with the circuit. The arrangement of electronic components should be possible dependent on applications like dynamic, aloof, and electromechanical.

In planning an electronic circuit following are mulled over:

Fundamental electronic components: capacitors, resistors, diodes, semiconductors, and so on.

Power sources: Signal generators and DC power supplies.

Estimation and examination instruments: Cathode Ray Oscilloscope (CRO),  multimeters, and so forth.

Classification of Electronic Components:

Electronic gadgets are part of our daily life. If you are as old as me, you might remember when you used to wait to use the phone booth to contact your friend after writing them a letter and stating when you could have a chat. Nowadays, you can hardly function if you forgot your phone rushing to catch that train as we are always tethered to them 24 hours 7days a week.

Anyway, back to electronic components. They are classified into two groups namely:

1. Active components: Active components supply current or energy in an electronic circuit and examples of these can be generators, alternators, diodes, transistor, voltage, MOSFET, Logic gates, and current sources.

What are active components?

Other examples of active components like amplifiers, vacuum tubes, and transistors will help us understand these basic electronic components. Active components tend to use external sources of power to add energy or power the circuit or system. In more simplistic terms, they control how electricity flows in a circuit.

•   Battery & Power Supply

•   Electric Generator

•   Emitters

•   Gas discharge tube

•   Ignitron

•   Thyratron.

  2. Passive components: These types of components receive the energy which it can store, dissipate in either a magnetic field or an electric field. You must have heard of resistors, inductors, transformers, and capacitors which are the most common examples of passive components.

 What are passive components?

As their name suggests they do not require energy like power to operate and ,therefore, do not provide gain and amplification to a circuit but rather attenuate.

Types of passive components:

•   Field-Effect Transistor (FET)

•   JFET (Junction Field-Effect Transistor)

•   MOSFET (Metal Oxide Semiconductor FET)

•   Diodes (All)

•   Rectifier Diode

•   Schottky Diode

NTP based digital clock panel driver

This project introduces an open-source, ATmega328 based, configurable NTP clock with a 2.3-inch, 7-segment display driver. This clock automatically obtains time from the configured NTP server and updates the date and time of the built-in RTC (real-time clock). If the connection to the NTP server is lost, the clock continues to run using its built-in RTC.

All the parameters of this clock can configure using its USB base serial terminal. The firmware of this clock supports both static and DHCP addressing modes. Apart from that, parameters such as NTP server address, time-offset, and clock display formats can change through the menu-driven configuration terminal. This clock is designed to drive large common-anode, 7-segment displays. The prototype version is assembled using four individual segments of 7.2V, 2.3-inch, red color displays (FJS23101BH). To archive, the necessary high output voltage and the current, the 7-segment display output stage of this clock is formed using ULN2803 Darlington transistor array and BC858 transistors. The network component of this clock is built around the ENC28J60 10BASE-T stand-alone Ethernet controller.

Highly accurate DS3231M RTC is using in this clock for time-keeping operations. To backup the date and time, the CR1220 type button cell is included in the PCB. The date and time are syncs with the NTP server during the system startup. Users can manually initiate synchronization by pressing the "SYNC" button in the system. Depending on the NTP server, the user needs to specify the time offset to the system to get the correct local time. Time offset can configure using the system configuration menu, and it must be input in a standard format like +5:30. Firmware of this clock is developed using the Arduino framework and libraries. PCBWay provides sponsorship for this project. The PCBWay online ordering service provides excellent help to fabricate this PCB. We got finished PCBs within three days, and the quality of the service is at a superior level. PCB of this project can directly order from PCBWay through this link.

This project is an open hardware project. All the project source codes, schematic diagrams, documentation, PCB designs, and compiled firmware files are available in the project GitHub repository.
