Hi, can anyone please tell me how to find out from the clap switch (using CD4049 and HEF4013) the time until the relay switch - CLAP period time - (how to calculate - which resistors/capacitors) ? And those that prevent false triggering ?
Of course it has false triggering.
The simple circuit cannot tell the difference betwwen clapping, hammering or gun shots. It might even be triggered by a dog barking.
