Sparki has an On/Off switch used to shut off battery power to Sparki.
How It Works
The switch behaves differently depending on whether Spark is plugged into an USB port or not. When Sparki is plugged into USB, the switch controls power from the battery to the motors. All other electronics will work regardless of whether the switch is turned on or not. When Sparki is not plugged into USB, the switch controls all power to Sparki.
