Octopus Analog Photocell Brick - Light Sensor dash Ultrasonic DistancePhotocells are sensors that allow you to detect light. They are small, inexpensive, low power, easy to use and don't wear out. For that reason they often appear in toys, gadgets and appliances. They are often referred to as CdS cells (they are made of Cadmium Sulfide), light dependent resistors (LDR), and photoresistors.
