# 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:
|
|
|
|
|
|
|
|
**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?
