This guide explores how to load files and run code on a MicroPython board. In the earlier introductions to MicroPython you manually typed all the code you wanted to run into the board’s serial REPL. This process is great for learning and experimenting, but not great for developing and running complex programs because you have to type in the program every time you want it to run. However MicroPython has an internal filesystem which can store code that’s run whenever the board powers up, just like an Arduino runs an Arduino sketch. Using a simple tool you can learn how to load code and other files into MicroPython’s filesystem and enable an ‘Arduino-like’ workflow for developing code on your computer that runs on a MicroPython board.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
