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. |
