I am currently working on a project that require me to trigger a relay when a specific sound is played through the set device. The general idea of a sound activated switch I have, but it triggers the relay on all sound that is played.
I circuit must trigger only when the specific sound (probably stored in memory) is played. An help or a nudge in the right direction will be appreciated
