Build a simple DIY clap switch

Description: Here’s a simple DIY clap switch circuit. The circuit is mainly composed of an audio frequency and a bistable trigger circuit. Q1 and Q2 together form an amplifier circuit. MK1 (electret microphone) accepts Clap/Audio signal and that enters to transistor Q1 through the coupling capacitor C1 and enters to Q2 base through collector directly after getting…
