David Johnson-Davies published another great project. It’s an IR remote that supports the most popular control protocols.
The IR Remote Wand is a universal remote control that you can program with up to five codes to control a variety of different products:
It supports some of the most popular IR remote control protocols: Philips RC-5, NEC, Samsung, and Sony. It’s based on an ATtiny85, and the circuit goes to sleep when you’re not using it, to avoid the need for an on-off switch and to prolong the battery life. You can use my earlier IR Remote Control Detective [Updated] to discover the codes for the functions you want to support.
