Electronic metronome

Electronic metronome“beats” the beats not only sound, but light pulses. In his scheme includes two transistor of different conductivity. The excitation amplifier is implemented by using positive feedback through the capacitor C1. The pulse repetition frequency — from 40 to 210 per minute — adjust the variable resistor R2. The amplitude — adjusted with resistor R5.
