LED Infinity Mirror Controller, 32 LEDs, Multiple Patterns using PIC12F675

LED Infinity Mirror Controller, 32 LEDs, Multiple Patterns

UPDATE: This kit is discontinued please see the new version, 8 Channel LED Controller v.3, the development files are still available to build this version.

As simple a circuit as can be. A 12F675 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.

It was designed to go along with my 8″x8″ 32 LED Infinity Mirrors.

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.

Kits, Including 32 LEDs, colors buyer’s choice, can be bought from my store  at www.ChromationSystems.com

More Updates and Info will be Posted to the 8 Channel LED Controller Webpage

The Eagle Schematics, PCB layout, and Source Code in Assembly can be purchased  all together in a Developer Package.

UPDATE: Code in ASM is available for download below, or on the Main Website

The Schematic, HEX File, and Datasheet are in the ZIP below.

Resistors, Capacitor & Sockets

Place the resistors first.

– R1 is a 10kohm (Brown, Black, Orange), 1/4w, it is the pull-up for the push-button switch
Schematic Infinity Mirror Controller
– 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.
– Depending the resistors may or may not sit flat on the PCB, if they are to big, just place them in like in the images below. Flip every other one so the leads are next to each other.

Place the Capacitor C1 next.

– It is not polarized and can be placed in either way.

Sockets are last, be careful placing them. Make sure all the leads get into their correct hole.
There is a notch in the sockets that should line up with the image on the top-side illustration.

Solder them in securely and watch for solder bridges between pins.
