Today I was tasked with building a line sensor for the Vex bot my partner and I are working on. It was a simple task which somehow lasted the whole day. It works by having a emitter and a phototransistor. The emitter shines a infrared light which would reflect off of a surface to be picked up by the phototransistor. The voltages will be higher the less infrared light is detected, and from there, the microcontroller can be programmed to react depending on that value. I managed to test and assemble the Line Sensor with minutes to spare.
I have yet to test if I properly soldered everything correctly.
