FM Radio

Project Number: 71

Description: Install the battery eliminator connector into the battery compartment in the FM radio, as shown. Connect the red & black jumper wires to the battery (B4). Plug the earphones into the radio, press the reset button, and then press the scan button several times to find a radio station (radio features may vary). Listen to the radio for a while. If the sound is distorted, then recharge the battery using the solar cell or the other power sources in this kit. With Snap Circuits Green, you can run the radio with the limitless and clean power from the solar cell, and you can also use the battery as a storage device. The radio can also be used with normal 1.5V "AAA" type batteries, but these would need to be replaced regularly.

Snappy: The radio is sending messages through the air using high frequency electromagnetic waves. It is like yelling to someone far away, but it uses very fast changes in electric/magnetic fields instead of slow changes in air pressure, and also using a tone that only someone tuned to hear it.
