So I was hoping to have my Spark Photon in hand by March, but they had some setbacks in manufacturing, and delivery has been pushed back til April. Standing in for the Photon then is the ever capable Arduino Pro Mini 328 - 5V/16Mhz.

I've tested each of the individual components I have on the Pro Mini one at a time, and so far they work wonderfully. I was initially worried about the Rotary Encoder, but after watching Kevin Darrah's video, I worked up the courage to wire it up and test it out. His code uses interrupts for the rising and falling of pins 2 and 3 on the Arduino, and after watching the numbers on the Serial Monitor dutifully increment and decrement as I spun that encoder, I was satisfied that this thing might just work.

I'm hoping to use the RGB and encoder as the only user interact able part of the TDM-SE-C. Pushing the button starts the user modifiable options like setting the clock, setting the wake time, setting the sleep time, with the color of the encoder letting you know what setting you are modifying.

Next I'll be piecing the Arduino code together for the Encoder, ChronoDot, and 4Digit-7Segment display and hit the Pro Mini with it, to see what flys.
