I'm in the early stages of making a pinball machine and I ran into a few problems trying to set up the ball trough. The ball trough uses opto switches and the transmitters work fine but the receivers don't work. The documentation says that it runs off of 1.7 volts. This would be fine, but the switch board only outputs 12 volts. The only solution I have thought to try is voltage dividing down to 1.7 volts. But before I go down that path I wanted to see if anyone else had a better solution or had the same problems?
