Arduino theremin concert

One of the arduino tutorials was for a theremin. With a few modifications I was able to properly express my sophisticated musical abilities. Enjoy! Arduino code follows (prolly doesn’t make TOO much sense without the wiring schematic… if there’s interest I’ll put up a picture). int sensorValue; int sensorLow=1023; int sensorHigh=0; const int ledPin=13; void setup(){ pinMode(ledPin,OUTPUT); digitalWrite(ledPin,HIGH); Serial.begin(9600); while(millis()<5000){… Read more →
