Via Twitter Nicholas Tollervey (@ntoll) – The latest #MadeWithMu blog post discusses Dilnaam D’s project under the watch of teacher Sean Tibor at Pine Crest School in Fort Lauderdale, Florida. Nicholas writes:
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.
As to the project:
Dilnaam’s project is a sort of interactive face mask, made with an Adafruit Circuit Playground Express, CircuitPython and Mu. The mask allows folks to become aware of and manage their stress levels (very useful for teachers!). Dilnaam explains:
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.

Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
