Application 7 ¾ Police car

This is a full program application example to demonstrate how Easy Format handles a complicated

design requirement. All the work is to be done on a single page.

There are four input trigger buttons and two output pins to drive two LEDs.

· BUTTON #1: Turn ON (START) or OFF the engine.

· BUTTON #2: Gas pedal to give ACCELERATION sound from idle and then keep on at a steady

running sound.

· BUTTON #3: SIREN sound On/Off: toggle ON and toggle Off.

· BUTTON #4: BRAKE, triggers deceleration sound and then brings the car to idle.

· LEDs OUTPUTs: Blinks in opposite phase when the Siren sound is on. That is when one light is on,

the other light is off in an alternating pattern.

· TIME OUT REQUIREMENTS: every sound needs to be automatically shut down after a specified

period if no more trigger signal is received.
