The Light Sensor uses a photocell that allows your robot to detect and react to light. With the light sensor, you can program a whole new range of capabilities to your robot. A Programming Kit is needed to change the program in the VEX Controller. Analog input of light levels.

What do light sensors do in robots?

A Light sensor is used to detect light and create a voltage difference. The two main light sensors generally used in robots are Photoresistor and Photovoltaic cells. Other kinds of light sensors like Phototubes, Phototransistors, CCD’s etc. are rarely used.
