Metronome Generator using NE555

Here is a simple circuit using IC NE555 which will be used to generate metronomes.Such a circuit is incredibly helpful to people who learns music. The circuit is nothing however an astable multivibrator wired around NE555 .The elements|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.
• The speaker k1 can be a n 8 Ohm tweeter.
