I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

We’ve featured loads of IR Arduino projects and they are all ... t have a programmable heating system. Maybe he will add a temperature sensor someday so it doesn’t have to run on strictly ...

The part list consists of one Arduino, two resistors, and one IR emitter. That’s right, an emitter. When an LED (IR or otherwise) is reverse biased it can act as a light sensor. The main ...

I made this Arduino project that allows to turn ON and OFF LEDs using a cheap IR remote control as ... buttons to find out what code does each button transmitts and then update the sketch to use those ...
