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…
USB powered mini speaker amplifier is conveniently powered by USB and it is simple to set up. USB powered speakers are convenient for listening to your media while at home or on the go. Conventional computer speakers that require an electrical outlet to work can be prohibitive because they force you to be close to…
This is a 4x100W audio amplifier board with Audio B plus Bluetooth module. It has integrated 2xST high performance TDA7498 chip which supports dual channel audio amplification. Each channel is capable of giving nominal power output simultaneously and continuously. This board can be powered by any DC 14V-39V* power supply.
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 tutorial- Sensor graph and LED controller together. You can also see one more similar experiment- Sensor graph and LED controller using Smart Phone- Arduino Shield. If you…

You can build simple LED chaser circuits using CD4017 and NE555 timer. There are hundreds of projects in the internet for making such simple LED chaser circuits.
TSA8635 is a compact size and easy to use Bluetooth audio receiver. This Bluetooth music receiver connects to the Line-In or Aux input on your home audio system. You can also stream audio from your Bluetooth enabled cell phone or mp3 player to your home audio system. Note: We can provide OEM/ODM service for…
TSA9840B is a 2x20W audio amplifier board with a new AudioB plus Bluetooth module that supports Apt-X. It has perfect class-D architecture (based on MAX98400A) and each channel has 20W power output. Both channels are capable of outputting nominal power simultaneously and continuously.
In this article, we are going to describe how you can use the “fully assembled clap_switch” to light up 100-240V appliances. When we say 100-240V appliance used with a clap switch, it is usually a bulb/lamp/CFL(Compact Fluorescent Lamp) tube. This article is for absolute beginners, so, we will try to explain all the small details.
I have taken this project from fritzing.org. This project has been released under creative commons license. This project can be useful Arduino beginners for learning 8X8 LED MATRIX. The experiment publisher has made a simple snake game. I have not tested this project, but I am sure that it should work on your breadboard also.
This project is similar to the following projects: 1. ON and OFF LED using infrared sensor 2. PWM experiment using infrared sensor For this particular and the above listed experiments, you need this library: arcfn.com/files/IRremote.zip See the following image to know how to fix the infrared sensor on the breakout board. http://arcfn.com/files/IRremote.zip#sthash.wIx2Q2Mr.dpuf http://arcfn.com/files/IRremote.zip#sthash.wIx2Q2Mr.dpuf http://arcfn.com/files/IRremote.zip#sthash.wIx2Q2Mr.dpuf Datasheet…
This is an LED flasher kit based on NE555 and 74HC595. The LEDs on this kit scroll and give a water flowing effect. The bistable circuit formed by NE555 and 74HC595 generates an oscillating pulse and adjusting the value of RP changes the oscillating frequency so that the flowing speed of the LEDs can be…
To make an object counter we can use a simple dark detector circuit and a normal calculator. Pole and NO (Normally Open) terminals of a relay have to be connected to the two pins which are used to activate ‘=’ key of calculator.
As we block the light falling on LDR, the calculator starts counting.
For the calculator to work as a counter, we first need to press ‘1’ and ‘+’ keys.
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…
