Metronome Generator Circuit using NE555

Here is a simple circuit with NE555 IC that can be used to generate metronomes.Such circuit is very useful for those who learn music. The circuit is simply an astable multivibrator NE555 cable around. The components R1, R2 and C1 determine the 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.
