Hi, I am very new to Arduino. I was wondering if I can use a small Arduino (such as an Arduino Nano) to switch channel ground pins (for a video receiver) and display channel information on a small oled display. On the receiver module, there are 5 pins that are grounded in different configurations to switch between channels. Usually they use DIP switches, but I want to have a screen with channel information and preferably a push button channel selector. Is this possible with just an Arduino? Would I need to add other components?
Thanks for any help!
Here is an example circuit diagram of the desired application. Can I use an arduino plus some other components in place of the SW1 switch?
