Hi! I was hoping someone might be able to tell if this idea could work. Is there any way that the MyoWare Muscle Sensor EMG could be converted to audio? I am hoping to convert the muscle signal to line level audio to send through an effects processor and record. Would I need some sort of amplifier? Any guidance would be greatly appreciated. Thanks!
You could write an Arduino program to listen to the analog value the sensor is outputting and then use the [Arduino tone command to vary the pitch of sound being sent to a speaker.
You would need an amplifier if a small speaker isn’t loud enough.](tone() - Arduino Reference)
