Hi, i have a matching pair of ir led/phototransistor that i want to use as an light switch. The problem is that the phototransistor's output is proportional to the strength of the ir light that it receives, so the mosfet that it drives has a dimming effect. How can i make it so that it only turns off or fully on?
Best regards.
