Yes it works! I was curious and have done this last week... The 'learning' remotes are capable of remembering the codes needed for your IR bricks. You can programm the RCX to sent a code (message) and let the remote learn this. Later on your RCX can (...) (22 years ago, 29-Nov-03, to lugnet.robotics)

I'm very new to the whole robotics thing so forgive me if the answer to my question is obvious. Can a universal remote, the type that "learns" the function of other remotes, be used to "learn" the functions of the Lego remote? and.. If the IR tower (...)
