I have a fixed roof light in my room that came with a remote control that can be fully taken apart. The remote control can switch the lights on or off using a radio system. I was wondering if there was any way to use my Arduino to control the remote control (through wires) to control the lights. I do not have any Arduino radio components so it would still need to go through the original remote. I have taken the remote apart and this is what it looks like:
The buttons are as follows: the top two (K1 & K2) buttons is to turn on/off a coloured LED but these are not important to me. The button K3 is to turn on/off the main light (I want the effect of this button being pressed to be created using the Arduino) and the button K4 is to turn all lights on/off.
