Awesome project + write-up from Jim Lee, who shared on Show & Tell back in April.
Looking at the FeatherFONA, I got the idea that making my own cellphone might be a fun project. I mean, it already does everything. All I needed to do was write some GUI code and there I’d be. From doing the calculator and doorbell, I had a bunch of GUI code libraries already written up. So, how hard could it be?
Ok, I knew it would be a bit of a stretch, I just, as always, under estimated just how much.
So I bought one of these little guys and when I had some free time, begin to experiment with it.
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.
