IDENTIFY THE VALUE OF RESISTANCE BY SOUND

In the project given here, we can measure the value of resistance(0ohm to 10me) by hearing sharpness of the sound. Connected the probes at the two ends of a resistances and listen to the sound produced by the circuit. Particular values of resistances produce a particular sound by which we can identify the approximate value of the resistances.

PARTS LIST
IC:555
Heater Rod,small size Fan
Resistance: 100k,LDR,control 5m
Capacitor: 100MF,12V,0.001
Diodes: IN4001
