This was the final project for "Electronic design and testing" lessons at school. I gained 20 out of 20 points for it.

File #375
RGB Led cube: 4x4x4 = 64 leds or 192 PWM channels

File #376
Chips used:
- ATMega88 microcontroller @ 16MHz,
- 3x TLC4941 16 channel Led driver
- MMA7455 accelerometer
- LM2734 1A buck converter
- LM4132 voltage reference
- AO3404 P channel Mosfet reverse voltage protection

File #377
The LM2734 1A buck converter + ON/OFF switch, reverse voltage protection (P-FET) and a 500mA resettable fuse.
- The 4 pin male connector is for a 2 cell LiPo battery.

File #378
Closeup on the MMA7455 accelerometer and the LM4132 voltage reference (left) and the TLC at the right.
- The battery voltage is measured to provide a low-voltage protection.
