Build the IR Receiver Circuit

If you have not used the IR Receivers with your cyber:bot before, take a look at the pictures below. The infrared receiver needs three connections: 5 V, GND, and an I/O pin to read the signal it sends.

  • Build the circuit as shown by this pictorial and schematic:

IR Remote breadboard wiring for the cyber:bot.

The circuitry inside the infrared receiver makes it safe to connect its signal pin to the cyber:bot PCB with a small resistor, even though the sensor is powered by 5 V
