Victor got a MMA7361 3-axis accelerometer breakout board from eBay and wanted to make something useful with it. So he made a modular board layered with PIC16F887 and blue LED one. The intent of it was to put it on a car for some nice effects due to acceleration but it stayed on a desk just to play around.
There are 48LEDs used in different direction layout – that’s 8 LEDs for every direction. They are driven using serial-in-parallel-out shift registers. There is also a beeper attached to beep once a 0G is detected.
