Learn CircuitPython using the Adafruit Trinket M0 HHV2020

Learn to code with CircuitPython on the Adafruit Trinket M0 hardware development board with step by step practice tasks.
Using several different circuits learn to control them with CircuitPython code examples for each.
This presentation was put together for the BSidesDFW 2020 Hardware Hacking Village.

I'm very grateful for this easy to understand video! You are clearly very knowledgable but also able to explain things in such a manner that a newbie's head does not explode from overload of information. Very happy I stumbled upon your channel. I will defiantly subscribe and check out your other tutorials!

Thank you.

Thank you for the video, I have a trinket that I purchased a few years ago but never used, so your video has inspired me to get it out and use it, so I appreciate that, please can you tell me where you purchased your orange USB cable from it looks handy for micro and C connection. Thanks, Bob in the UK

GREAT video! If you wanted to connect a wire from a camera that required you to ground a wire for half a second to trigger a photo capture what module/ pin would you use? Also, I have read somewhere that the SDA pin is by default in open drain pulled to low(down to ground)...activate pull up with the internal resistor?

In case you haven't solved this already: I'd suggest using the digitalio library, an available digital pin, and set it to be pulled up by default, and then set it low for half a second when you want to (see 19:28 in the video for some example code). There's a document by Tony DiCola on AdaFruit's learn guide called "CircuitPython Basics: Digital Inputs & Outputs" that you may find helpful. I'll try posting a link in a reply (separating it in case links are auto-moderated), but a search should pull it up (pun intended ;) )
