I'm working on a project using the UNO where I want to detect if something moves between an infrared emitter and transmitter, similar to the way that we could tell if something passes between a photoresistor and LED.
For this, I've purchased these parts:
I'm fairly new to Arduino, and am not sure what to do. All tutorials that I've seen are very complicated, and involve using a remote control to input infrared signals.
Are these the wrong parts? Is there something I'm overlooking?
