Tell us about yourself!
I think your problem is the connection of the "SIG" and "-" output of the MyoWare Sensor.Just switch the Yellow and Red cabe in the Breadboard. And also the Polarity of the Capacitor is Backwards the gray line is negative and goes to GND.And that sould work.
Thanks!Actually one of my goals is to make that. Stay tuned :)
Did he use the MyoWare Sensor? or did he tried to build his own?. Also the speaker shouldn't be a issue as long as it isn't a big one. Even a buzzer works for this.
