I read with interest here this post: How can I use an Arduino to simulate button presses on this PCB
I am a beginner in this and I am trying to learn how to do this based on a small remote control I would like to simulate a fake press using an arduino.
I am also not sure if I need to use a MOSFET as it is a very small device requiring little amperage so I think a small transistor will do ?
Basically, I would like Arduino to send a signal to the 2 red points here that will simulate a fake button press.
Hope I am making sense here. I appreciate any guidance or pointers on what I need to make this happen. Thanks !
More details to share: With COM on Battery-Negative and the other lead:
on the right side of the button = 12V. When button is pressed = 12V
on the left side of the button = 0V. When the button is pressed = 12V.
I will just focus on one button. Disregard the other button.
