Turning on a buzzer
What else can you use your IR receiver to do, besides turning on an LED? You can also use it to turn on a buzzer, as shown in the diagram below. Just replace the LED in the original IR receiver circuit with a buzzer, making sure to attach the black (-) wire from the buzzer to the (-) terminal ofo ne of the batteries, and the red (+) wire to the long (+) wire from the black reciever.
