The unit that controls the color of the LED. This is done by twisting and/or pressing the illuminated knob. Due to the encoder being completely mechanical depending on how fast I turn the knob between the notches the wave forms will be longer or shorter. To change how much Red, Green, or Blue appears in the blade all you must do is twist the knob. To change between Red, Green, or Blue functions is done by pressing the knob down.
The unit that measures the acceleration of the lightsaber in the X,Y and Z axis.
The micro controller that controls the whole circuit. The Arduino Nano is the brain of the entire circuit.
