Hi,
I am trying to build a sound sensor for my Lego RCX. If i hook the mic to the rcx inputs directly its not sensitive enough I practically have to blow as hard as i can on the mic to get the values to go up.
I am looking for some sort of circuit that would amplify these values so that I can tell my RCX to do something via sound from a reasonable distance.
any suggestions? Thanks
