Hi,
I am new to the forums. I am trying to read a signal with a microchip. However the microchip has a max input of 5v. The incoming signal is a square wave (0v, 12v). At the end of a hi pulse, it spikes to 40volts or even more. Id really appreciate it if someone could tell me what components I would need to put in that circuit to drop it down to (0v, 5v), and block out that spike.
Thanks,
Steve
