AdaFruit makes an adorable tiny little Circuit Python IoT device called the PyPortal that’s just about perfect for the kids – and me. It a little dakBoard, if you will – a tiny totally programmable display with Wi-Fi and lots of possibilities and sensors. Even better, you can just plug it in over USB and edit the code.py file directly on the drive that will appear. When you save code.py the device soft reboots and runs your code.
I’ve been using Visual Studio Code to program Circuit Python and it’s become my most favorite IoT experience so far because it’s just so easy. The “Developer’s Inner Loop” of code, deploy, debug is so fast.
As you may know, I use a Dexcom CGM (Continuous Glucose Meter) to manage my Type 1 Diabetes. I feed the data every 5 minutes into an instance of the Nightscout Open Source software hosted in Azure. That gives me a REST API to my own body.
I use that REST API to make “glanceable displays” where I – or my family – can see my blood sugar quickly and easily.
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.
