The Game of Shouting Match

This is an electronic game project that measures the intensity of a sound burst. A microphone picks up the sound and triggers an electronic "scoring" circuit that lights up a string of ten LEDs to show the sound intensity. To make it fun, the LEDs will light up one by one, accompany by an increasingly higher audio tone. If full scale is reached, it will have a dramatic effect of flashing all LEDs with accompanying high pitch.

You will learn how to use operational amplifiers (LM324) and comparators (LM339) as basic building blocks to make Voltage Controlled Oscillator, ramp generator and sound signal amplifier. A specialty IC LM3914 is used to drive the LEDs indicating the sound intensity level.
