Light Sensor Photoresistor Module for Arduino
A typical photoresistor circuit will require a voltage divider circuit and output the signal into the analog pin of the Arduino. If you have a microcontroller that has no ADC integrated, this unit will automatically convert that signal into digital. Use the on board potentiometer to adjust the sensitivity.
Holding the board with the pins facing towards you, the left most pin labelled DO connects to any digital pin available. The middle pin goes to ground and the right most pin labelled VCC goes to 5v source.
