Electronic Metronome circuit schematic

This metronome circuit schematic is not modern but is cheap and reliable. The well known 555 is presented in this metronome circuit and produces regulated impulses which can be heard at a speaker. The metronome frequency can be adjusted with P1. The power supply is a 9V battery and if you use a 8Ω speaker insert a 33 – 100Ω / 1W resistor in series.
