I love it when I can get my wife roped into these things! Was able to get my hands on a couple more Raspberry Pi’s…in telling my wife what these things are capable of the wheels start turning in her head…”Could you have them watch birds make a nest in a birdhouse?” Of course I can!
So…what did I need? I needed a Raspberry Pi (of course)….the Pi NoIR camera and an infrared LED. I ended up steeling an LED off an old little toy helicopter I had that broke. The radio used LED to talk to the helicopter. I knew I could use this someday! You could use an old TV remote as well. Make sure to pay attention to + and – leads on it when you’re taking it apart…because it does matter!
It only took one ir led for me. Hook the negative (-) of the led to a 200ohm resistor (red black black for the colors…220 ohm or 200 will work) and then put the other end of the resistor on the ground pin of the GPIO on the Raspberry Pi. Then put the pos (+) of the led on the 5v of the GPIO of the Pi. Do this while it’s not turned on of course.
