Introduction

“Microsoft MakeCode brings computer science to life for all students with fun projects, immediate results, and both block and text editors for learners at different levels.” (Hands on computing education, retrieved August 22, 2019).

Makecode looks similar to Snap! and Scratch, i.e. it is a visual programming language. It also allows saving and working with JavaScript code.

Adafruit MakeCode

The online MakeCode editor at AdaFruit, is https://makecode.adafruit.com/. The site includes some walk-through tutorials and some examples. The platform includes that familiar palette with programming elements, a workspace for the program, and a simulator to the left.

So far (Aug 2019), it works with the Circuit Playground Express board of the Adafruit FLORA system. Code can be directly downloaded into board via USB. It will be compiled into some kind of machine language.

The following code will activate on shaking the board and repeat four times a sound and a blinking (from blue to red/yellow) since one ring is shown one after the other.

AdaFruit MakeCode example for Circuit PlayGround Express

The corresponding JavaScript code is

input.onGesture(Gesture.Shake, function () {
    for (let i = 0; i < 4; i++) {
        music.magicWand.play()
        light.showRing(
        `blue blue blue blue blue blue blue blue blue blue`
        )
        light.showRing(
        `yellow red yellow red yellow yellow red red red yellow`
        )
        pause(500)
    }
    light.clear()
})
