Octopus Analog Photocell Brick Adjustable Sensitivity

What is a photocell?
Photocells 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.

Adjustable sensitivity Analog Photocell Brick allow you to adjust sensitivity of analog Photocel to get digital signal or set a trigger value. 

It's all the same use with Analog Photocell Brick.



The Freaduino Sensor Shield is the perfect shield to connect this senor to Arduino. Or Freaduino UNO which we had pre-stray Octopus Brick interface.
