Using Parts as Conductors

Project Number: 58

OBJECTIVE: To show that motors and lamps may sometimes be used as ordinary conductors.

Description: Turn on the slide switch (S1) and tap the whistle chip (WC), it makes a machine gun sound (with music in the background). Thoroughly cover the photoresistor (RP) with your hand and the sound becomes a siren. After a while the sound will stop, tap the whistle chip and it resumes. Press the press switch (S2) and the LED (D1) lights, but the lamp (L1) does not light and the motor (M1) does not spin. Electricity is flowing through the lamp and motor, but not enough to turn them on. So in this circuit they are acting like 3-snap wires.

(NOTE: This is the circuit printed on the kit's box cover, but you may place the fan blade on the motor (M1), but the fan will not spin, too.
