This guide will teach you how to setup and use your RobotGeek Geekbot Core or Basic Kit.
This guide will refer to the RobotGeek Geekduino, the Arduino Compatible microcontroller recommended for use with RobotGeek products. However this kit will also work with the Arduino Uno, or other Arduino variants like the Seeeduino.
Are you ready to dive even deeper into the world of Arduino? Then take a look at Robotgeek 101! RobotGeek 101 is a step by step guide that will teach you how to build, wire, and program your Geekduino/Arduino. Through RobotGeek 101 you will learn the basics of Arduino like digital input and output, and move on to more advanced topics like PWM and servo control. By the end of RobotGeek 101 you'll be well equipped to start modifying our demo code and creating your own custom applications.
If you have the RobotGeek Geekbot Basic Kit, centering your 9G mini servo is a necessary step before you start building your Geekbot. To begin centering your servos, we're going to have to set up your test rig. This is incredibly easy to do with a RobotGeek Sensor Shield, which was included in the Geekbot Basic Kit. Start by attaching your Sensor Shield to your Geekduino/Arduino Compatible board. Slot the bottom pins of the RobotGeek Sensor Shield into the terminals in the top of the Geekduino. Note how the boards seat evenly on top of each other, and the pins line up exactly. Be careful not to bend the pins.

For assembly in the Geekbot Basic, you will need to set the 9G servo to 90°. The following sketch will move the servo to about 65°, then to about 115%deg; and finally stop at 90°. If you would like to re-start the process, either reset the Geekduino or unplug/plug the power into the unit.

In the video below we show the servo with a horn attached so that it is easy to see the movement. You do not need to attach your horn at this time (you will do this in the assembly guide).
Note: The RobotGeek Continuous Rotation Servos (Wheel Servos) included do NOT need to be centered.
See this page for more information and a video on centering servos.
