Currently, I have a control board that I want to control using a microcontroller. Currently, this board works by choosing a program by pushing and releasing one of the buttons on the right, and then click the most left button to start the program. I'm thinking of hacking the board by removing the physical button switch, and somehow use the microcontroller to emulate the button push and release instead, and then delay for a second, and then emulate the button push and release on the start button. Is my concept doable? if so, how should I wire the board?
concept wise, it should be similar to using a relay to short and cut off the circuit. but it seems like a relay will be too overkill?
