  • LDR (Light Dependent Resistor) also known as photoresistor is a resistor whose resistance varies with the amount of light falling on it. This is a small size LDR with a size of 5mm.
  • To use, connect one pin of the photo cell (either one, it has no polarity) to power (for example 5V) and the other side to your microcontroller's analog input pin. Then connect a 10K pull-down resistor from that analog pin to ground. The voltage on the pin will be 2.5V or higher when its light out and near ground when its dark.
  • This sensor can be used for making a light sensor, color sensor, object sensor, line sensor, etc
