This circuit uses 12F675 to controls a high-power shift register, which in turn controls up to 48 LEDs at 20ma per, (~120mA per channel) in 8 channels(groups),Software controlled patterns create seamless effects from group to group. With 4-state greyscale ( 4 states of LED of brightness ) a vast amount of patterns/effects are possible.




A single momentary-pushbutton cycles through the programmed patterns. Comes loaded with 5 patterns, and the ability to add more through re-writing the firmware.





R1 is a 10kohm (Brown, Black, Orange), 1/4w, it is the pull-up for the push-button switch
R2 - R9 are the resistors for the LEDs.The values of R2-R9 vary depending on the Color of the LEDs and the amount per channel.
