clap switch

need help want to turn on a light with the clap of the hand well versed in pic 16f84a20p

the problem is the minute voltage (50mv) from the the mic driver circuit is there a way to use this voltage to input threw a pic pin to turn on another





thanks to any smarter minds than mine

Solution 1. Use an amplifier to increase the signal level to something that the PIC Input will trigger on.

Solution 2. Pick a PIC with internal Comparators (easiest) or ADC (a little more tricky) which can then work with signal levels down in the range you have got.
