TSA1110 is a smartphone Bluetooth audio volume controller. It has integrated a digital potentiometer and a powerful Bluetooth and its control distance is up to 30m (outdoor). After it gets connected to your audio amplifier, you can use an Android or iPhone App to control the audio volume from the smartphone. There are 3 ports for…
This project describes how to build an IR remote control extender / repeater to control your electronic appliances from a remote location. An IR detector module receives IR signal from remote control and two IR leds are re-emitting the signal to the appliance. You can place the IR emitting leds close to the device you…
We have been using different online Gerber viewers for checking our Gerber files before sending the PCB designs for manufacturing. We have now started using EasyEDA’s Gerber viewer because it helps us to visualize the PCB that would appear after it is manufactured. The application is pretty straightforward and we can check different files to see the changes on…
This small module helps you measure moisture of soil. It is a low cost sensor that you can purchase from Ebay. To modify the sensitivity of the soil moisture sensor, just rotate the potentiometer on the module.
TSA1200 has a dedicated remote control, but if the remote control is broken or you want to use your own remote control, this tutorial will teach you how to pair. Note:Â The remote control used must meet the carrier frequency of 38KHz and support the NEC standard. Hardware and Software required: audio amplifier board connection cable…

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 a basic electronic DIY kit for beginners. The kit generates a light explosion effect with several LEDs. The scrolling of the LEDs is controlled by CD4017 and NE555. You can adjust the speed of the explosion using a potentiometer. You need basic soldering skill to build the kit. It takes about an hour…
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.
In this tutorial, we will learn to use a 16×2 LCD with Arduino. The following image shows the pinout of 16×2 LCD. Components required for this project: Name Quantity Component U1 1 LCD 16 x 2 R1 1 Potentiometer 10k U2 1 Arduino Uno R3 R2 1 220 Ω Resistor
Before making an Arduino programmer on breadboard using FT232RL, you need to know about arduino, breadboard and USB to serial FT232RL break out board. If you are an electronic novice, I recommend you to visit this page to get ideas on building simple electronic projects on breadboard.
In this tutorial, we will turn on and off the LEDs sequentially, such as Christmas tree lights.
With this project/application, you can make a light sensor dependent lamp. You can make a light sensor or dark sensor with this application. The light sensor of your Android smart phone senses ambient light present in your room and sends commands to Arduino board. Your Arduino program determines the behaviour of the LED, whether it…
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.Â
This is the first experiment for Amarino shield.
