Sometimes, I use an external editor (usually Sublime Text) to work on larger projects, and I like to be able to both compile my code (to verify) and then upload to my device (one of many different Feather M0 boards). I have a “Build System” in Sublime Text to compile my code, but I always had to switch over to the Arduino IDE to compile. This annoyed me, so I wrote a NodeJS script that finds the Feather, resets it into bootloader mode, and uploads the .bin.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
