The document describes the design and implementation of an electronic gesture recognition system using an accelerometer to control a robotic arm. The system uses an ADXL335 3-axis accelerometer attached to a human arm to capture gestures. The accelerometer outputs analog voltages that are converted to digital signals and transmitted wirelessly to an LPC1768 microcontroller. The microcontroller controls a KSR10 robotic arm in response to the received signals. Experiments showed the system could successfully control the robotic arm movements in both dynamic and static modes using human gestures detected by the accelerometer.
