I've got a LCD for my CarPC project and I want to make automatic switching between RCA (reverse camera) and HDMI input (Raspberry Pi).
I am thinking of controlling input micro switch with Arduino, but I don't know how.
You need to make 3 clicks on input button to go to RCA and or HDMI input.
Can it be done?
Is it as simple as connecting a transistor in parallel with microswitch and coding arduino so the transistor "clicks" 3 times?
PS: I hope I choose a right subforum...
