Yes my servos are indeed the cheap ones, I'm using 25 of them for my project.
Steve,
I mapped the numbers I was reading from the sound sensor, in a second attempt
I tried refining it by 20 instead of 30
int Rcvd[] = {85, 86, 87, 88, 89, 90, 91, 92, 93, 94};
int Pos[] = {0, 20, 40, 60, 80, 100, 120, 140, 160, 180};
I got a little better results. It doesn't do just 90 degrees.
What movements ? any movement will do.
What bpm ? I can choose slow music, maybe a Waltzer, a tango.
Can I read the values directly from the output pin that feeds the speaker and not use a sound sensor microphone? Stupid question ??
