LDR Based DC Motor Speed Control

A light-dependent resistor (LDR) whose resistance is inversely proportional to the intensity of light is often used as a sensor in electronic projects that involve the use of light. This LDR based DC motor speed control project uses an LDR to control the speed of a DC motor. The objective of this project is to see how much faster the motor moves when a hand is brought closer to it. This circuit could be ver ...
