Simple Color Detection Circuit

The video tutorial explains a circuit using a red LED and a photoresistor to detect color changes, such as determining produce ripeness. It covers the principles of light reflection and absorption, the function of circuit components like photoresistors and MOSFETs, and demonstrates using a multimeter. The tutorial also discusses calibrating the circuit for specific applications, such as agriculture, where it can detect when produce changes color as it ripens.
