The Zumo shield has several jumpers that let you change the way it is connected to the Arduino, as shown in the picture below.

* The '''battery level jumper''' connects the Arduino’s analog pin 1 to a voltage divider circuit that allows you to monitor the Zumo’s battery voltage. This jumper is disconnected by default and can be connected by soldering a short length of wire between the two holes.

* The '''buzzer control jumper''' connects one of the Arduino’s PWM outputs to the buzzer on the Zumo Shield. This {{underline|jumper is disconnected by default}} on both the assembled and kit versions of the Zumo robot; it must be connected to enable the buzzer.

If you have an Arduino '''Uno''' or an older Arduino (with an ATmega328P or ATmega168 microcontroller), you should jumper the two holes bracketed with the label '''328P''' to connect the BZ pin to digital pin 3. If you have an '''A-Star 32U4 Prime''' or Arduino '''Leonardo''', you should jumper the two holes bracketed with the label '''32U4''' to connect the BZ pin to digital pin 6. These are the pins our ZumoBuzzer library expects the buzzer to be connected to for each respective microcontroller. More details about the buzzer can be found in Section 3.a.
