Lucky Break #2: Christine, the manager of the Taza Chocolate Bar, was game. 

In our first meeting she radiated a quiet, no-nonsense practicality: she listened to my futuristic ramblings, deftly insert a question or suggestion, listened some more, then added a few more suggestions.

Most of the time, her ideas bumped the project up a notch.

Her best idea: Why not tune the display to Taza? Instead of moving a flagman’s flag, why not spin an image of a granite grinding wheel. Granite grinding wheels are what Taza uses to create their gritty chocolate. 

Christine even had an idea for the background image, which she shot with her phone while we were standing there: the machine that pulverizes the ground cacoa beans into chocolate.

I looked at the image on her phone. Liked it. 

She sent me it to me.

The new modification required a slightly different servo, a continuous servo, which can rotate in two directions, instead of going to fixed points. I ordered one for around $12 from Adafruit

The servo code just needed a few simple changes, to accommodate this new capability. You can check the code out on GitHub

Next - Why? Connectivity.
