This video is an answer to a question raised by viewers of the previous video on the subject of "IR transmission and reception. Instead of having an IR transmitting keypad, we use a common IR Transmission Module, available widely - the one in this video I found inside the Polytech's kit, S1. So this video is also a demonstration on how to transmit ANYTHING useful in the IR spectrum to be able to communicate it, to other receiving equipment.
Have fun and get inpired!
