TSA1010 is a digital stereo Bluetooth/Single-ended audio volume controller board. It has two 3.5mm audio jack and a BVC port. You can use it to control the audio volume of any normal amplifier board. The audio out signal will increase/decrease when a user rotates the knob and Bluetooth audio volume control port will also output an…
This is a Bluetooth audio receiver with phone call function. There are two 3.5mm audio jacks and a phone call answer button on the board. It can work as a normal Bluetooth music receiver. When this Bluetooth music receiver connects to the Line-In or Aux input on your home audio system, you can then stream…
This is yet another dark sensor DIY kit. It is slightly different from other dark sensor kits. It has a buzzer and a photodiode that makes it different from other kits. Along with the LED, the kit turns on the buzzer whenever it senses darkness. See all the images below to get the idea for…
Change The BT module audio gains All of our Bluetooth audio amplifier boards and Bluetooth audio receiver boards use AudioB plus module as the core bluetooth receiver module. If you have to use a mismatch speakers or power supply in your system(size limit or other reasons). You may want limit the maximum output audio gains…
TSA7510B is a 2x100W audio amplifier board with a new AudioB plus Bluetooth module that supports Apt-X. It has perfect class-D architecture(Based on TPA3221) and each channel has 100W power output. Both of channels are capable of outputting nominal power simultaneously and continuously. This board can be powered by any DC12V-30V power supply. It can be used to drive…
We can use the logic of making an automatic light detector to make a simple water level indicator.We just need to remove LDR from the circuit and put the wires into water, then it simply works as water level indicator. There is a specific resistance between the wires that are dipped into water and conduction of electricity through water gives biasing voltage to base of transistor.
The sensitivity can be adjusted using VR1. Put 470K variable resistance in VR1.
TSA3118B is a 2x50W audio amplifier board with a new AudioB plus Bluetooth module that supports Apt-X. It has a perfect class-D architecture (based on TPA3116D2) and each channel has 50W power output. Both channels are capable of giving output power simultaneously and continuously.
This project is a Mini Stereo Audio Amplifier based on TDA2822 IC. DESCRIPTION The dual low power amplifier built around TDA2822 8pin DIP. IC, it is mainly designed to use in portable players, radios and other building block project. A 3V supply can be used to drive headphones providing 20mW in 32 Ohms per channel, and a…
The AM2302 (also known by DHT-22) is a low cost humidity and temperature sensor with a single wire digital interface. The sensor is calibrated and doesn’t require extra components so you can get right to measuring relative humidity and temperature. The AM2302 can connect directly to the Arduino Uno.
This is a heart shaped Bicolor multiple LEDs DIY electronic kit with Happy Birthday music tune for absolute electronics beginners. This kit gives you a lot of ideas about bicolor LED, buzzer, music chip, transistors, and resistors.
This shield enables you to interface many different devices to Arduino Nano using optically isolated inputs/outputs. The circuit consists of 4 Input channels and 4 Output channels and all 8 I/O lines are optically isolated. This project can help in various industrial applications where EMI noise and high voltage lines can damage the Arduino Nano or other circuits connected…
Description: In this clap switch we use three different modules given below. It is necessary to make these three modules in order to make a clap switch. a. Dark sensor using 2 transistors. b. Monostable mode of 555 timer. c. Toggle switch using 555 timer.

When you press an infrared transmitter or normal TV remote control near TSOP1738 infrared sensor, the 555 timer configured in monostable mode gets triggered.
This is yet another dark/light sensor project that uses a photoresistor. This kit has an LM393 chip and there is a relay also. It is a light operated switch. 【Great School Science Project】: The light operated switch can be a great school project for children. It is widely used to help students learn basic mechanical…
There is an in-built equalizer in Tinysine Bluetooth 5.0 module. If you have the CSR USB-SPI programmer, you can change the equalizer settings by yourself. TSA6175 module uses the CSR8675 Bluetooth chip. It needs a new version software to change the EQ settings. This tutorial will teach you how to set it. Hardware and Software required: Tag-Connect…
DOWNLOAD IN PDF- LINE FOLLOWING ROBOT USING ARDUINO AND INFRARED LED This project has been derived from LDR based line following robot. I strongly recommend that you first try line follower robot using LDR, I found that the LDR gives better results than infrared sensor.
