SPECIFICATIONS Supply input : 6 VDC @ 200 mA Output : Speaker, 8 Ω / 0.5 W Audio amplifier type LM386 with volume control preset Jumper selectable…
DC Output Solid State Relay 10Amps 60V DC (Optically Isolated Input) This project has been designed around TLP250/352 which is Opto-Coupler IGBT/MOSFET Gate Driver from Toshiba and Mosfet IRFP260 from IR, This relay consists of optically isolated gate driver and low impedance Mosfet. The combination of low resistance and high load current handling capabilities make this Relay suitable for…
Step 1: Download USBtinyISP driver software from Adafruit.com. Install the driver for the USBtiny device. Then, insert the new Atmega328P-PU chip on the DIL socket of Arduino board. Connect the USBtiny device to Arduino.
TSA6014 is a compact size and powerful Bluetooth audio receiver. This Bluetooth music receiver connects to the Line-In or Aux input on your home audio system. You can then stream audio from your Bluetooth enabled cell phone or mp3 player to your home audio system.
AMP-1 amplifier uses TDA2822MÂ as an amplifier chip. This chip is STMicroelectronics (ST) developed dual-channel monolithic power amplifier IC, usually used in the pocket cassette player (WALKMAN), tape recorders and multimedia speaker for the audio amplifier. It has a simple circuit, produces good sound quality, it has a wide voltage range and other characteristics that…
This is the second time I am writing an article on how to use the fully assembled clap switch that I designed in 2014. This time, I have put several images and written explanation on each of the images so that you can use it easily. At the end of the photo gallery, you can…
Description: In this project, Arduino first encodes the remote signals and decodes them to control LED brightness. First of all, connect the Infrared sensor as shown in the picture below. Then, press keys 0 through 4; Arduino stores the values for keys 0 through 4 and when the sketch runs, key 0 turns off the…

We are now selling BLUE colored DIY Arduino kit. Â You know that there are several versions of Arduino hardware. Hobbyists have also made Arduinos on strip boards giving different looks. Here’s one more Arduino, that is a simple do-it-yourself (DIY) kit. It is just like any other Arduino UNO board. However, it does not…
This is one of the most interesting experiments that uses Amarino shield and Amarino toolkit application. If you have never heard of Amarino toolkit and the shield, we recommend you to go the following pages: About Amarino toolkit About Amarino shield This experiment with Amarino shield is similar to our previous tutorials on Sensor Graph-…
This is the second experiment for Amarino shield. If you do not know anything about Amarino toolkit or this shield please click on the following links: About Amarino toolkit About Amarino shield You can get a list of other experiments at the end of this post. Before you try this experiment, we recommend you to…
This experiment makes the use of  ‘Android- Arduino BTCOMM Shield’  and Amarino. If you are not familiar with the shield, visit this page. This experiment is similar to my previous tutorials on RGB multicolor lamp using Amarino. and RGB multicolor lamp with custom Bluetooth ID on Amarino Interface. If you have never worked with Amarino, I strongly…
LCD is very important part of many DIY and industrial projects. The 16X2 LCD shield has been designed to develop LCD related projects using 28-40 Pin Pic development board or DSpic development board, along with LCD this shield includes LMD18201 DC Motor driver , 2 Trimmer potentiometer and 4 tact switches with jumpers. Jumpers can be…
This is yet another ultrasonic range finder project using Arduino. We have done several similar projects in the past. It allows us to control a buzzer based on the distance detected by an HC-SR04 sensor, making it sound with a frequency proportional to the distance from an obstacle.
A relay is an electrically operated switch. Current flowing through the coil of the relay creates a magnetic field which attracts a lever and changes the switch contacts. The coil current can be on or off so relays have two switch positions and they are double throw (changeover) switches. The relay’s switch connections are usually labeled COM(POLE), NC…
This is one of the simplest and easiest experiments using Bluetooth Module , Android and Arduino. You just need an Android serial emulator, any type of emulator should work for this experiment. I recommend Blue term , you can find this application on your Android Market (Google Play).
TSA6175 is a Bluetooth 5 multipoint audio receiver. You can have many TSA6175s paired and work together. You can also let it work like a normal Bluetooth audio receiver. This Bluetooth music receiver connects to the line-In or Aux input on your home audio system. You can then stream audio from your Bluetooth enabled cell…
