Overview
CdS cells are little light sensors. As the squiggly face is exposed
to more light, the resistance goes
down. When its light, the resistance is about 5-10KΩ, when dark it
goes up to 200KΩ.
To use, connect one side of the photo cell (either one, its
symmetric) to power (for example 5V) and
the other side to your microcontroller's analog input pin. Then
connect a 10K pull-down resistor from
that analog pin to ground. The voltage on the pin will be 2.5V or
higher when its light out and near
ground when its dark.CdS cells are little light sensors. As the
