Inventors Kit Experiment 5 Further Help -intro-870

This further help resource contains download links for additional code examples and also a walk-through video that covers the experiment in full. The video also has hints and tips to help you complete the experiment.  

Inventors Kit Experiment 5 - Using The Accelerometer To Control Motor Speed :

The BBC micro:bit has a built-in accelerometer. The accelerometer detects if it is speeding up or slowing down in 3 directions, labelled below as X, Y and Z. Each axis can measure between -4096 and 4096 which correlates with -4 and 4Gs. A G is an acceleration of 9.81 meters per second per second; this is the acceleration that objects under the influence of earth’s gravity experience.

Code Downloads:

The code examples below have been individually zipped and can be downloaded by clicking on your preferred option. Once unzipped you can either open the and edit the code in appropriate editor or place the HEX file onto your microbit*.

MakeCode Editor & Python Code Downloads:


Legacy Editors Code Downloads:

NOTE: The legacy editors will disappear at some undisclosed point in the future. The code can still be placed on a microbit and will run regardless but you won't be able to use an editor. When that happens, switch to using one of the currently supported editors. We've already made the switch as the new editors are better and more fully featured. * - To place the unzipped HEX file onto your microbit, connect your microbit to your computer via USB and then open File Explorer (Windows). Your microbit should show up as a removable drive. Simply drag and drop your HEX file onto the microbit in file explorer and the file will be transferred. The power light on the back of the microbit will start to flash, once the flashing stops the microbit is ready to run your code.  

Booklet Errata:

The current version of the BBC micro:bit booklet is 1.3. If you have version 1.1 then please see below for corrections made to the current version. When creating the Touch Develop Script:
  • To add a new variable called 'Tilt' select 'var (new variable)' and change the default name to 'Tilt'.
  • To add the input -> acceleration code delete the default '0' and then use the commands within the 'input' command set.
  • To use the Tilt variable delete the default value and then select the 'Tilt' variable.

Hi Owen, when you click on the Math menu item it will display a list of blocks. Also, when you click on Math in the menu the word 'More' will appear under the work Math in the menu, click on the word More, and you will find the block you are looking for in there. I hope this helps.



I am trying to code this experiment but when I go in the math section the 'absolute of' block isn't there. If anyone could help me a would really appreciate it Many thanks, Owen

Hi Tara, if you were to drop an email to one of our customer service team will try to help you.



Hi there, This is a great kit but the manual disappeared and we are only half way through! Is the manual itself available online anywhere? Many thanks!
