Project #11

OBJECTIVE: To build a circuit with sound and light.

Sound & Light

OBJECTIVE: To show how capacitors store electrical charge.

Electricity BankProject #12

Build the circuit, place the base grid centered on the

Rover body, and connect the jumper wires as

shown.

Turn on the switch (S1) and electricity flows

from the batteries through the circuit. The horn (W1)

converts electricity into sound and the LED•(D4)

converts electricity into light. The four 1KΩ resistors

(R2) are connected in parallel, to act as a 250Ω

resistance.

Build the circuit and connect the jumper wires,

leaving one end of the green jumper off as shown.

Touch the loose end of the green jumper to point A

on the 3-snap wire for a moment. The horn (W1)

makes noise while the 100μF capacitors (C4N) fill

up with electricity.

Now move the green jumper from point A to point B

on the 2-snap wire. The LED•(D4) lights for a few

seconds using the electricity stored in the

capacitors. Move the green jumper back to A to refill

with electricity, and then to B several times.
