The aim of this project is to develop a circuit that can count the number of people entering and exiting a room using two Infrared (IR) sensors connected to an Arduino UNO. This bidirectional counter ...

I made this Arduino project that allows to turn ON and OFF LEDs using a cheap IR remote control as a preparation for the next big step: disassemble my girlfriend’s chinese LED lamp and replace its ...

How to connect the TSOP4838 to an Arduino to read the transmitted codes By using a cheap integrated IR receiver/decoder device (the venerable TSOP4838), most of the hard work is done for you!

The remote control is used to turn the Pi on. The Arduino reads the IR code from a remote and simply powers up the Pi.
