Here is the diagram of my Arduino infrared close proximity sensor. As you can see, the core part of my experimental setup is an Arduino UNO, but other compatible microcontrollers can also be employed.

Analog pin A4 is for the temperature sensor, digital pin D2 is for the infrared receiver ... fades an onboard LED (D4) in the multifunction shield using the analogWrite() function: int testLED = 10 // ...

We’ve featured loads of IR Arduino projects and they are all exciting ... before adding the retrieved codes to a Teensyduino setup and programmed to receive and decode the remote’s IR signals.

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 ...
