Standalone
This Arduino Pump Tutorial shows a simple example of how to use a float switch and RobotGeek Pumping Station to refill a reservoir once the level gets too low. For our example we use a small aquarium, but this same project could be used for pet dishes, water fountains, or any other number of similar applications. The Pumping Station is a RobotGeek kit which packages a small liquid pump and relay. To operate a pump using an Arduino microcontroller you need a relay to switch on and off a separate power supply.

PC Control These demos and projects allow the robot to be controlled via a computer.

ArbotiX Commander Control - These demos and projects control the Robot using the ArbotiX Commander, the handheld Arduino based remote control.

Direct Control - These demos and projects control the Robot directly from sensors connected directly to the Robot's control board.

Pose Control - These demos and projects allow you to create and playback a sequence of poses.

Serial Control - These demos and projects control the robot using a serial packet protocol.

Standalone - These demos and projects are deisgned to let your robot function without a computer or additional microcontroller.

Wireless Control - These demos and projects allow you to control the robot wirelessly - usually by replacing the Serial Connection with XBee modules.

Reference - These articles have technical details regarding the control and operation of the robot.
