Hello people. i'm new to this forum and this is my first post I need to drive an optocoupler from my motorcycle's battery. Battery voltage is 12 to 14.4, depending on the engine revs. can i drive the optocoupler with this voltage? Or do i need to limit the voltage? The optocoupler's output will only light up a 3v LED. which optocoupler should i use? 4n25?
Thank you
