So a little background on what I am doing. I have a remote control that I would like to adapt to be switchable by an attiny flashed to arduino. I have both the attin84 and the 85 chips to select from. The remote control utilized a 12volt L1028 battery. The remote uses a surface mount tactile switch on the negative battery terminal.
I'm very new and am still learning what im doing. My first thought would be to use a 12v relay with 5 volt coil in place of the switch. But I am not sure that's the best way to go about this. Ultimately I would like to replace that tactile switch with something else that the attiny can trigger.
any suggestions on that something else?
Thank you
