Arduino LDR (light dependent resistor) automatic light circuit
Using an Arduino to control a high power COB LED strip light based on measuring the light level using a light dependent resistor (LDR).
This uses a voltage divider circuit to create an analog voltage based on the light level. It then uses a MOSFET switch to control the high power COB (chip-on-board) LED strip light.

This also uses a MOSFET switch which is explained in detail in my Disco Light video at • Electronics MOSFET Switch control disco li...
