38 KHz Breadboard IR Transmission

Posted May 25, 2011 by Chris

This short but sweet article details out the circuit and parts needed to build a basic IR transmitter and receiver circuit all on a breadboard. The circuit is built to transmit at the standard 38 KHz carrier frequency used in most IR systems. The design does only a simple thing, that is it blinks an led when a button is pressed. A simple yet good project for entry into the wireless world.
