Medallion: Circle LED Animation PIC16F628A

This project uses the Simple LED Animation Kit (SLAK post or page) with the LEDs arranged in a circle around the PIC16F628A. I decided to do this project after picking up some red SMD LEDs at HSC in Santa Clara, CA, last week.

Summary of Medallion: Circle LED Animation PIC16F628A

This project adapts the Simple LED Animation Kit (SLAK) for a circular layout using a PIC16F628A microcontroller and red SMD LEDs. Designed to function as a wearable medallion or Iron Man reactor core, it operates on 4.5V powered by three AA batteries. The creator is currently refining animations specifically for the circular arrangement and offers potential modifications to convert components from surface-mount to through-hole technology.

Parts used in the Circle LED Animation PIC16F628A:

  • Simple LED Animation Kit (SLAK)
  • PIC16F628A microcontroller
  • Red SMD LEDs
  • Circuit board with circular design
  • LED socket
  • Three AA batteries

LED AnimationAlthough the only difference from the basic SLAK is the board design, I find that this layout to be have the potential to be more useful. It could easily be a medallion on a necklace. If I had blue LEDs this would go well in an IronMan Reactor Core package.

This board only needs 4.5V and in the video is running on only 3 AA batteries. You can see that the PIC is still in a socket.

If anyone is interested, I can easily change the SMD parts to thru-hole parts and post an updated board.

Schematic LED Animation

I am still refining the current set of animations for both a linear (straight line) arrangement and a circular arrange. I need to tailor the ones running on this board for a circle only.

  • How does this project differ from the basic SLAK?
    The only difference is the board design, which arranges the LEDs in a circle rather than a linear pattern.
  • What voltage does this specific board require?
    This board only needs 4.5V to operate.
  • Can I power this project with batteries?
    Yes, it can run on just 3 AA batteries providing the required 4.5V.
  • Is the PIC microcontroller soldered directly to the board?
    No, the PIC is still placed in a socket.
  • What are some potential uses for this circular layout?
    It could easily serve as a medallion on a necklace or fit into an IronMan Reactor Core package.
  • Are there plans to change the component types?
    The author is willing to change SMD parts to thru-hole parts if requested.
  • Are the animations designed for other layouts compatible with this board?
    No, the animations need to be tailored specifically for the circular arrangement running on this board.
