Test the setup to make sure it is working.

Have the controller flex his/her forearm. This should make the LEDs on the SpikerShield light up as far as the red lights.

If the LEDs do not light up, either double check the setup or turn up the gain on the SpikerBox by turning the orange potentiometer screw counterclockwise.

You should see muscle action potentials on the tablet screen each time the controller flexes the wrist.
