Step 11 Connecting the muscle sensor(s) to the Arduino

Now we're getting close. By this step, your muscle electrodes and power supply should be hooked up to your muscle sensors. We just have to connect the sensors to the Arduino.

Using the solid core wire/jumper wire, connect the Vout pin of each muscle sensor to the analog pins on your Arduino.

Sensor 1 Vout --> Analog pin 0
Sensor 2 Vout --> Analog pin 1
Sensor 3 Vout --> Analog pin 2
Sensor 4 Vout --> Analog pin 3

Then connect the GND pin of muscle sensor 1 to the GND pin on your Arduino and the GND pin of muscle sensor 2 to the Analog pin 3 of your Arduino. That last part will keep the remaining two analog pins from floating along with your sensor 4's output.
