Using Photoresistor From Raspberry PI To Detect Light 4 (1)

A photoresistor (also known as photocell) is a Light Dependent Resistor (LDR). As the name suggests, these components act just like a resistor, changing their resistance in response to how much light is falling on it. Usually, photoresistors have a very high resistance in near darkness and very low resistance in bright light. This component […]
