Here is easy circuit using IC NE555 which will be used to generate metronomes. Such a circuit is extremely useful to people who learns music. The circuit is nothing however an astable multivibrator wired around NE555 .The parts R1,R2&C1 determines the output frequency.
Notes.
- The circuit can be wired on a general purpose PCB or common board.
- The circuit can be powered from a 9V PP3 battery.
- The POT R1 can be used to adjust the rhythm of the sound.
- The POT R2 can be used as volume control.
