Josh Johnson (http://jjmojojjmojo.github.io/) presents: "In building novel human/computer interaction devices using CircuitPython (http://learn.adafruit.com/welcome-to-circuitpython), a fork/port of MicroPython (http://micropython.org/) for the Adafruit M0 and M4 series development boards (http://www.adafruit.com/product/3333), I had a lot of state and state changes to work with. In this talk, I'll be exploring what state is, and how to use familiar Python constructs available to us in Micro/CircuitPython to model it, track it, and respond to changes. We'll cover a common task in electronics projects, button de-bouncing, but also explore a pattern we can extend to any sort of input, and use to cover general state tracking. It's essentially the fundamentals of what UI frameworks do in desktop environments. We get the opportunity to build what we need from scratch due to the limitations of our platform. The audience is people who basically know basic Python. :) No prior experience with micro-controllers or electronics required."
"We'll construct a simple demo circuit and control an RGB led. In the talk we'll walk through the basic construction and then dig into the code. Feel free to bring a laptop and a CircuitPlayground Express or other compatible board to mess around with the concepts during the talk!"
Extemporaneous "lightning talks" of 5-10 minute duration are also welcome and don't need to be pre-announced.
Park in the municipal deck on the other side of the Arts Council across W. Morgan St. The after-meeting will be around the corner at Bull McCabe's Irish Pub. Come join us for a fun and informative evening.----
