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.
