16 red, 16 green and 16 blue LEDs. Microcontroller ATmega32 @ 16MHz. This first version of the software works without any timers or interrupts but does PWM to mix colors and fade brightness. Only 3 IO ports are needed: data, clock and enable. The colorbar has 8 x 74LS164 to "drive" the 48 LEDs. Later I'll add 16 white LEDs and improve the software, so that any animations will be possible - not only from left to right ;-)
