It was decided that it would be easier to put a socket for an Arduino Pro Mini on the circuit board rather than laying out all the components and soldering them in place. Ordering the components and installing them on each board would be less expensive but could present problems with programming. The Arduino Pro Mini used in the first prototype needed to be unplugged from the components before it would accept programming.

No footprint could be found for an Arduino Pro Mini so instructions were found for making a custom device. The instructions were not easy to follow or very helpful so a link will not be provided. Most of the work was done by experimenting.

The device was built in two parts, the schematic version and the footprint. The schematic version was not drawn with real dimensions or an accurate layout of the pins. The footprint reflected the actual dimensions of the Arduino Pro Mini. A digital caliper was used to accurately measure the spacing of the pins.

Schematic version of the Arduino Pro Mini

To do:
  1. Plot out location of all lights for even distribution
  2. Create circuit board
    1. Designate all components
    2. Design schematic of components 
    3. Design layout for single layer board

The rest of the posts for this project have been arranged by date.
