• First PCB I have ever designed in EAGLE CAD, soldered together precisely made LED Cube Matrix.
• implemented a program to utilize software PWM for persistence of vision and a dimming effect simultaneously.
• Used a Multiplexed design to allow for only 20 ports on a micro controller to run the cube and each LED separately.
• Programmed in BASIC using for loops using the principles of PWM and persistence of vision to quickly pulse each horizontal layer on once at a time over and over in a for loop creating one frame in an animation.
• The human eye cannot see fast enough to see that multiple horizontal layers are never on at once during the animation.
