The title of this post is misleading. A few paragraphs in he writes:
"I quickly began to write Arduino code to simulate a failing BBU. I also wrote some code that acted as a DAC to take in the signals from the BBU."
Should really be titled "How I won a Facebook hardware hackathon"
The final demo didn't include any code. Writing the code for the arduino was a waste of time in terms of what we actually build. The main part of the post was about the pivot and how we won with a simplified codeless solution
