Multi Power

Project Number: 10

Description: Build the circuit shown. Set the meter to the 5V setting. The meter measures the voltage produced by the windmill, solar cell, and hand crank, which are connected to work together. You can change the meter setting to 50mA, to measure the current produced.

Snappy: The red & yellow LEDs (D1 & D5) are used here to keep the different power sources from interfering with each other, by controlling the direction electricity flows.
