There is a power source of 75V and I want my Arduino to acknowledge when a switch has been activated. Such as when a switch closes it can read that it has been closed and perform a certain action. Is the use of a optocoupler good for this since there are no mechanical moving parts thus no possible switch bouncing? Or would it make more sense to use a buck converter to step it down to 5V and just have a SPST and have the Arduino read that instead?
