Controlling Things Based on Light Intensity

PIC12F683 with LDR

A PhotoCell or LDR (Light Dependent Resistor), used in a circuit, allows controlling things based on light intensity. Here is a circuit showing how to wire an LDR and┬ádemonstrates how controlling things based on light intensity is possible with a little help from a microcontroller. The thing being controlled in this circuit is simply an …
