wobbly lamp

Lamp which reacts to movement by changing colors.

It associates red, green and blue components with X, Y and Z axes respectively. The deflection from

initial position is linearly converted to light volume in each axis and returns to normal with

decay adjustable by a potentiometer unless the lamp gets bumped again.

Hardware required:

	* 12V supply,

	* MMA7361 accelerometer breakout board,

	* RGB LED strip or other similar light source with common anode,

	* 50x50mm single layer board to make the PCB,

	* electronic components as listed in the KiCad project (ATmega8, 3×N-FET, 3V3 regulator and

	  a bunch of resistors, capacitors and connectors),

This project aims to be an example of ATmega MCU's use of:

	* PWM (pulse width modulation),

	* ADC (analog to digital conversion),

	* interrupts (timer and ADC),
