Electronic Metronome Circuit with 555

This metronome circuit is not modern but is cheap and reliable. The well known 555 is connected as an astable multivibratos in this electronic metronome and produces a regular train of impulses which can be heard with a speaker. The metronome frequency can be adjusted with P1. The power supply is a 9V battery and if you use a speaker with an impedance of less than 8Ω insert a 33 to 100Ω/1W resistor in series.
