Summary

This circuit is designed to control three white LEDs using an LDR (Light Dependent Resistor) module. The LEDs will light up based on the output of the LDR module, which is powered by a 9V battery. The LDR module detects the ambient light level and controls the LEDs accordingly.

Component List

1. LDR Module 3 pin

   • Pins: VCC, GND, DO
   • Description: A light-dependent resistor module that outputs a digital signal based on the ambient light level.
