Infrared detector help?
I have 2 infrared detectors (like the one in picture) with 3 pins and want to make a simple detector to turn power on and off. The reason is that I want to make a line following robot. I only need to be able to put enough power through it to power a relay on or a transistor.
Please help I need to know what all of the pins do and how to use them. Or even better a curket dyagram that turns power on and off by infrared without using micro processors.
