I am working with some of my students on a Science Olympiad project. Electronics beyord resistors and capacitors is not my strong point. I am looking for a simple IR transmitter- receiver combo. We can use a standard TV remote but that would take up a lot of space. I looked through a box of parts left behind by the previous physics teacher and I have some of these https://www.amazon.com/Digital-Receiver-Transmitter-Arduino-Compatible/dp/B01E20VQD8.
Can someone provide a simple circuit diagram that a novice might be able to follow that will allow this to act as a simple switch. I also have some relays https://www.amazon.com/gp/product/B00VRUAHLE/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1 lying around.
I don't have any transistors but can order some if I know what to get.
If these parts aren't usefull let me know what to buy and if I can get all the parts for under $20 I can order them.
All I need is to use an IR beam to be dectected 20cm away which then turns something on. Only constraint is max 9V and we have limited overall size for the entire device.
