Features

  • Working principle: When no light is irradiated onto the photoresistor the triode is turned on, and the buzzer gets power and starts to chirp.
  • When light is shining on the photoresistor, the triode is turned off, the buzzer is powered off, and the tweet is stopped.
  • Here the triode is used as an electronic switch.
