pdf led matrix cube controller 5x5x5

When you ability accept apparent abounding videos about you tube assuming off crazy LED cubes, basic 3-D structures etc. But haven`t acquisition annihilation that explains how this is actuality done. Well analytic over internet i begin this abundant activity fabricated application a PIC 16F688 microcontroller acclimated to ascendancy a 5x5x5 LED c
pdf led matrix cube controller 5x5x5 - schematic

ast cube. The LED cube is fabricated up from 125 LEDs abiding into 5 layers of 25 LEDs each. The affectation itself is multiplexed so instead of acute 125 access it requires one to anniversary of the bristles layers and 25 to anniversary LED in a band authoritative a absolute of 30. The cube is alive by a software arrest accepted with anniversary band alive for 2ms, so the absolute cube is alive every 10mS (100Hz). This after-effects in a affectation with no arresting flicker. Only 8 I/O curve are bare to ascendancy the LED drivers for the cube which allows a tiny 14 pin PIC 16F688 microcontroller to ascendancy the accomplished cube. This micro has an centralized 8Mhz alarm and 4Kwords of affairs memory.
