Sean is one of the co-hosts (along with his colleague Kelly Schuster-Pared) of the excellent Teaching Python podcast. I’ve been working through the available episodes and constantly find myself grinning like the Cheshire Cat as I’m reminded of my own experiences as a teacher (of music), and learn how this talented duo of pedagogical pros practice the art of teaching technology, and especially Python. I heartily recommend you take a listen.
This mask was made to demonstrate how a Circuit Playground Express could be used to measure body temperature and indicate stress levels. My theory is that body temperature is an indicator of stressful feelings and that people can better control their stress when they have a visual indication of their own stress state.
In the picture (above), we can see see Sean bravely acting as a test subject as (presumably) Dilnaam looks on while making adjustments to the code in Mu. A teacher acting as a test subject for their students shows a wonderful sense of trust. This is great to see! 🙂
Dilnaam’s code is beautifully simple and well commented. Mu’s plotter feature is used to monitor the test subject’s temperature.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
