Project #22

OBJECTIVE: To build a police siren that is controlled by light.

Build the circuit shown on the left by placing all the parts with a black

1 next to them on the base grid first. Then, assemble parts marked

with a 2. Finally, insert the parts with a 3 last on level 3.

Cover the photoresistor (RP) and turn on the slide switch (S1). A

police siren with music is heard for a while and stops, then you can

control it by covering or uncovering the photoresistor.
