Full analogic circuit to detect 2 claps and activate a relay. Plug in whatever you want to the plug. Avoid others sounds-noises.

    can you share the schematic with us?

  • @daxweb I don't know how to share it....btw it's an amplification (with fet opamp) and a band-pass filter (with same fet opamp). Then the output trigger 2 "555" for timing, and the output of last "555" activate a bjt and the relay.
