Simple Photocell Diagram - Electronics tutorial about light sensor including photocells ldr one simple use of a light dependent resistor is as a light sensitive switch as shown below which have no crystalline structure and can generate currents of between 20. Then the point between the fixed pulldown resistor and the variable photocell resistor is connected to the analog input of a microcontroller such as an arduino. In operation a photocell acts like a light sensitive resistor with a high resistance when dark and a low resistance when in the light the schematic below shows the basic photocell circuit except rather than digital i o pin 1 connect to one of the analog input pins for ex le analog pin 1 as shown on the arduino.
