Project #95 Everything Circuit
This project combines several circuits to
demonstrate what you can do with Snap
Circuits
® Green.
Assemble the circuits shown. Install the
battery eliminator into the battery
compartment of the FM radio and connect
it to the circuit. Plug in the earphones, turn
on the radio using the volume knob and
press the scan button to find a radio station.
Set the meter (M6) to the 5V setting. See
page 4 if you would like to set the time on
the clock (T2).
The battery (B4) runs the radio and clock,
while the meter (M6) monitors the battery
voltage. Turn the hand crank clockwise to run
the horn; pushing the press switch makes the
horn louder. Place the solar cell (B7) in
sunlight or near an incandescent light bulb to
light one of the LEDs (D1 & D5), depending
on the slide switch (S5) position.
Note: You should not connect the jumper
wires to the LED circuit if you want to run
them using the solar cell.
The LEDs may also be powered by wind or
liquids. Assemble the pivot and place the
motor with wind fan on it. Connect it to the
circuit near the solar cell using the red & black
jumper wires. Blow on the wind fan or place it
in a strong wind to use it to light the LEDs.
To run the LEDs using liquid, assemble the
liquid energy source using the instructions on
page 4. Move the red and black jumper wires
from the windmill motor to the electrodes (red
wire to the copper electrode, black wire to
zinc electrode). Fill the compartments with
cola or juice. The solar cell is still connected
to the circuit, so you may cover it to prevent it
from helping the liquid run the LED.

There are many ways
to generate electricity,
and many more ways
to use it!
