A tutorial on How to make an InfraRed (IR) proximity sensor circuit along with detailed explanation on how the circuit works. The sensitivity or Range of detection can also be...

A tutorial on how to make an LED chaser lights (or) sequential LED flasher circuit on a breadboard using 555 timer + 4017 IC and a few other components. The LED’s chasing...

This project is on how to make a simple flashing/blinking LED circuit using transistors on a breadboard. watch the video for detailed step by step instructions on how to build this...

In this project we will make a Touch on Touch off switch circuit using 555 timer IC on a breadboard. This circuit has two pairs of touch conductors. Touching one of the conductor...

This project is to flash/blink two LED’s alternatively at an interval of around 500ms. The circuit uses 555 timer IC along with a few other electronic components and is built...

A simple InfraRed(IR) receiver circuit using TSOP1738 IC. Also known as remote tester, this circuit can turn on LED whenever any button on the remote control is pressed. The heart...
