|
Coding challenges for the glowing pendulum tutorial. #docs
|
||
|
|
|
||
|
|
## Before we get started
|
||
|
|
|
||
|
|
Complete the following guided tutorial:
|
||
|
|
|
||
|
|
* [tutorial](/microbit/lessons/glowing-pendulum/tutorial)
|
||
|
|
|
||
|
|
At the end of the tutorial, click `keep editing`. Your code should look like this:
|
||
|
|
|
||
|
|
```
|
||
|
|
basic.forever(() => {
|
||
|
|
let acceleration = input.acceleration("y")
|
||
|
|
acceleration = math.abs(acceleration)
|
||
|
|
acceleration = acceleration / 4
|
||
|
|
led.setBrightness(acceleration)
|
||
|
|
led.plotAll()
|
||
|
|
})
|
||
|
|
```
|
||
|
|
|
||
|
|
**Challenge 1**
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
Hold the BBC micro:bit in your hand in a dark room. Move the BBC micro:bit like a pendulum, and produce a slow image that captures the pattern of the BBC micro:bit LEDs.
|
||
|
|
|
||
|
|
**Challenge 2**
|
||
|
|
|
||
|
|
Replace "y" in `[input->acceleration("y")] with "x" or "z". Changing the axis will cause the BBC micro:bit to measure the force in a different direction. What differences in the resulting pattern does this replacement make?
