Foamyguy - Circuit Python 2020

I dipped my toes into the community about a year ago when I created the Android CircuitPython Editor and wrote the learn guide(my 1st!) for it. Admittedly, looking back it's something I wish I could've spent more time in 2019 on, but alas real life and work took up a bit more of my time.

One of the things that kept me busy was a project for work. We built an IO input board using a Trinket M0 as the brain. It takes trigger signals from a reed switch and sends them into an Android device that is playing video content on a nearby display. The trigger signals are ultimately used to play different content on the screen. We deployed around 200 of these in stores across the US. It was the first time we have deployed any custom hardware (albeit relatively basic!). The existence of the Micropython and CircuitPython ecosystems were a huge help in allowing us to do something like that with such li
