Hi guys,
I am trying to light up two leds using a remote control. The - button for the green led and the + button for the red one. It all works fine but the leds toggle on and off everytime I press the related button. What I want is to have the leds lighted up as long as I press the button and to have them go off when I release the button.
This seems to be tricky for which I miss the experience yet.
Anyone of you to help?
I know that it can be done. Somewhere I have seen something similar but using a different and older RC library so that wasn't a big help for me.
Any help is appreciated. Below I have pasted a listing of the code.
Regards,
Marcel
