# glowing pendulum blocks challenges
|
|
|
|
Coding challenges for the glowing pendulum tutorial.
|
|
|
|
## Before we get started
|
|
|
|
Complete the following [glowing pendulum activity](/lessons/glowing-pendulum/activity) and your code should look like this:
|
|
|
|
```blocks
|
|
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?
