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 @boardname@ in your hand in a dark room. Move the @boardname@ like a pendulum and produce a slow image that captures the pattern of the @boardname@ LEDs.
Challenge 2¶
Replace "y" in acceleration(y)
with "x" or "z". Changing the axis will cause the @boardname@ to measure the force in a different direction. What differences in the resulting pattern does this replacement make?
