We are going to explore a bit of MicroBlocks through making a festive ornament using a Circuit Playground Express.
Not only does MicroBlocks support whole programs, but any valid snippet can be immediately executed on the board. That includes prototype blocks on the palette as well as code under construction. This lets you interactively see how code works, piece by piece as you work on it. This is much like CircuitPython’s REPL, but more powerful. For those with an interest in programming languages, this capability is much like what Smalltalk provides: being able to execute any valid code at any time.
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.
