Coding

Importing Python Libraries​

From the Imports menu which is found under the Basic menu, select and drag a from microbit import * block to the code area and attach it to the # start code here block.

Creating Steps Variable​

WHAT IS A VARIABLE

Think of a variable as a box that stores information that can be used throughout our program. We give variables a descriptive name so we and others can understand what is going on within our program.

  1. From the Variables menu, select New variable…. Give it the name steps press Enter.

  2. From the Variables menu, select and drag a steps = 0 block to the code area and attach it under the from microbit import *. Select r and pick **steps.

Creating a While Loop​

From the Loops menu which can be found under the Basic menu, select and drag a while True: block to the code area and attach it under the steps = 0 block.

Creating the Shake Function​

  1. Select Logic from the Basic menu, Select and drag an if True: block to the code area and attach it within the while True: block.

  2. From the Accelerometer menu, select and drag an accelerometer.was_gesture(‘shake’) block and attach it within the True of the if block.

Creating the Shake function

Increasing Steps​

From Variables, select and drag a steps = 0 block to the code area and attach it within the if accelerometer.was_gesture(‘shake’) block. Select r and choose steps . Select the = and choose +=. Change the 0 to 1.

Pausing the Code for 500ms​

From Statements within the Basic menu, select and drag a sleep(1000) block to the code area and attach it below the if accelerometer.was_gesture('shake') block. Change 1000 to 500. This will pause your code for half a second.

How to pause your code

Resetting Steps to 0​

  1. From Logic within Basic, select and drag an if True: block to the code area and attach it under the sleep(500) block.

  2. From Buttons, select and drag a button_a.was_pressed() block to the code area and attach it within the True of the if block.

  3. From Variables, select and drag a steps = 0 block to the code area and attach it within the if button_a.was_pressed() block.

Displaying Steps on the LED Matrix​

  1. From Display, select and drag a display.scroll ("Hello World") block to the code area and attach it under the if button_a.was_pressed() block.

  2. From Variables, select and drag a steps block to the code area and attach it within the "Hello World" of the display.scroll () block.
