Use this activity document to guide your work in the glowing pendulum tutorial

Answer the questions while completing the tutorial. Pay attention to the dialogues!

1. Why are you creating a 'forever' loop?


2. Write the line of code to measure the acceleration with respect to the "y" axis and store this value in a local variable called 'acceleration'.


3. After storing the acceleration in a variable, write the code to take the absolute value of the acceleration, and store this value inside 'acceleration'.


4. Write the code that uses the acceleration value from question #3 to set the brightness on the BBC micro:bit.


5. Write the code that tuns all the LEDs on (as the image displays below)
