Wearable tech for halloween - The gemma MO's embedded python lets you change your code on the fly [Resources_Tools]

Halloween is approaching, and with it a global parade of costumes. So I thought this would be the perfect time to try out a new wearable microcontroller from Adafruit Industries: the Gemma M0. Adafruit has been putting out wearable microcontrollers for several years. These differ from conventional controllers, such as the Arduino Uno, in that the wearables are typically more compact and use pads with large through holes for input and output, instead of pins. These holes make it easy to sew boards to fabric or tie conductive thread to the pads. What makes the Gemma M0 particularly interesting is that it runs CircuitPython, Adafruit's modified version of the Python language designed for embedded devices. (At this point, I should note that Limor Fried, the founder of Adafruit, is a member of IEEE Spectrum's editorial advisory board, but she played no role in the origination of this article.).
