glowing pendulum blocks challenges

Coding challenges for the glowing pendulum tutorial.

Before we get started

Complete the following glowing pendulum activity and your code should look like this:

basic.forever(() => {
    let acceleration = input.acceleration(Dimension.Y);
    acceleration = Math.abs(acceleration);
    acceleration = acceleration / 4;
    led.setBrightness(acceleration)
    basic.showLeds(`
        # # # # #
        # # # # #
        # # # # #
        # # # # #
        # # # # #
        `)
});

Challenge 1

Hold the micro:bit in your hand in a dark room. Move the micro:bit like a pendulum and produce a slow image that captures the pattern of the micro:bit LEDs.

Challenge 2

Replace “y” in acceleration(y) with “x” or “z”. Changing the axis will cause the micro:bit to measure the force in a different direction. What differences in the resulting pattern does this replacement make?
