DescriptionEdit

Follow the instructions on the LIRC Receiver Web page for building the receiver.

  • Then, add U3,R2 and LED to your circuit.
    • U3 is an inverter
      • Attach the Vdd or Vcc pin to the Output of the voltage regulator
      • Attach the Vss or Gnd pin to the Ground pin of the voltage regulator
      • Attach one of the inverter pins, A1, to the IR receiver's output
    • Resistor, R2
      • Attach the pin of output of that inverter to the resistor, R2
    • LED
      • Attach the resistor to the positive of the LED
      • Attach the negative of the LED to ground
