Are you tired of carrying around one remote for the TV, one for the DVD player, one for the sound system and the list can go on. There is the possibility to buy one “good for all” remote control but it will cost you a few hundred dollars, off course there is an alternative for less money, make your own DIY universal remote control.
Any valid RC5/RC6 will be displayed on the LCD, and any code can be sent with the on board IR led’s, the LCD is the common 2×16 HD44780 compatible type.
The hardware is very simple, the software is written in basic and made available by the author.Â The Dell TV deals page sometimes has universal remotes like the Logitech Harmony One for heavily discounted prices.
I recommend this project for those interested about the RC5/RC6 codes, it can be a great alternative for radio based remote control for robotics, as you can see in one of my previous articles: IR remote robot
