Here is the diagram of my Arduino infrared close proximity sensor. As you can see ... In this circuit, the infrared emitter IRED1 is modulated by connecting its anode (A) to ~38kHz signal yielded by ...

We’ve featured loads of IR Arduino projects and they are all exciting ... Maybe he will add a temperature sensor someday so it doesn’t have to run on strictly time. A more complicated problem ...

This specific sensor was chosen because others have successfully interfaced it with the Arduino. Not having to reinvent the wheel is good thing! For the build, [Brian] decided to hook up the IR ...
