Introduction
When electric power
was first used to light up streets at night, someone in
each street became in charge of turning on the light at
nights and turn it back off in the mornings. Today
electric eyes automatically turn on the lights when it
becomes dark. Electric eyes are used for security in the
banks, shopping malls, warehouses and industrial
buildings. They are also used for safety of workers and
automatically stop machinery if the worker takes his
hand toward sharp blades. |

Material
and instructions
Have hands on
electronics and make some electronic circuits using an electric
eye. Light sensor, light meter and remote control light are
among the items that you may make during your experiments.
You may control any electrical device such as a light or a radio
or a fan using an electric eye circuit. Depending on your
project plan, you may need some or all of the following:
Photocell, Transistor, Diode, Relay, wire, bulb, socket,
battery, mounting board. |
