How to Analyze Your Running Arms With Tech #WearableWednesday #wearabletech #Arduino #fitness

Milan Gary was curious what her arms were doing when running. As a busy grad student at Parsons School of Design, The New School, running is an activity that helps to give her energy (and keep her sane). For a mid-term project, she decided to dive into wearable tech for answers.

Our arms ultimately control how fast we run and our posture. Sprinters and long-distance runners use different arm movements due to the change in their stride. So I thought, what if I could create a device that’ll detect when your arms aren’t at the right angle thus alerting the runner to adjust. So I started on the adventure of creating this device.

For her first prototype, Milan created Mathletic, an arm sleeve that reacts to movement using an Arduino, conductive fabric and an LED. The way the conductive fabric pads are set on the sleeve results in a very specific movement of the arm, and that was intentional.

…my mom broke her elbow a couple of months ago and to regain full extension she needs to do an exercise every day. This exercise is exactly the range of motion that you see the girl in the video doing.

The fun part about this project is that there is a bonus. Much like having friends cheer you on at a race, Milan added a servo to the project that rotates a cheerful flag when the arm exercise is executed correctly. This was specifically for her mom, to offer encouragement with her healing. I think with Milan’s tech skills, she may be able to create a wireless version of this sleeve and translate that flag into gaming. Can you imagine if physical therapy went that direction? There would be no more complaints about doing exercises and people may actually start posting their results on social media. I hope Milan received the “A” she deserves for this project and I’m wishing her mom a speedy recovery. Wearable tech is a great way to analyze body motion and for those that are interested in creating their own projects, check out our learning guide for Circuit Playground’s Motion Sensor. Circuit Playground has a ton of sensors built-in and it’s easy for beginners. Get started on your wearable!

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

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.
