This Arduino Sketch is the standard LittleArm firmware. It can be used with either the Android or Desktop Applications via bluetooth or USB
This is the Arduino sketch for the LittleArm 2C. This software allows serial control of the LittleArm with either USB or bluetooth. All code is heavily commented to aide education.
The primary Arduino Sketch for controlling the LittleArm Big arduino robot arm with either the bluetooth app or desktop programs.
This sketch allows control of the LittleArm 2C with the LittleArm Waldo. 
The SensorCube is a sensor that provides proximity data from 3 different directions allowing for control of the LittleArm in 3D or of the individual joints
Training Arm is an arduino program which takes input from potentiometers in order to control the position of the arm. Meant to be used with the LittleArm Trainer Hardware
This is the most basic demo of the ultrasonic Sensor. This code commands the arm to raise and lower based on distance of an object from the sensor.
