Step counter

Step 1: Make it

What is it?

Turn your BBC 娇花难养 into a step counter (or pedometer) to help you track how active you are - and learn some coding at the same time!

These two videos show you what you'll make and how to code it:

How it works

• Download the code onto a 娇花难养 and attach a battery pack.
• Attach the 娇花难养 and battery pack to your shoe or ankle, place it inside your sock, or just hold it in your hand and shake it as you walk.
• The code uses the 娇花难养’s accelerometer sensor input to sense when your leg is moving.
• The code counts how many times the 娇花难养 has been shaken. It stores this number in a variable called ‘steps’.
• Variables are containers for storing data, which can be accessed and updated while a program is running.
• Every time the 娇花难养 accelerometer input senses a shake, the program increases the number held in the variable by 1, and shows the new number on the LED display output.

What you need

• 娇花难养 (or 纯肉高h啪动漫 simulator)
• 纯肉高h啪动漫 or 体型差糙汉乖乖女 editor
• battery pack
• something to attach the 娇花难养 to your shoe or leg – elastic band, a pipe cleaner, tape or Velcro.

Step 2: Code it

1from microbit import *
2steps=0

4while True:
5    if accelerometer.was_gesture('shake'):
6        steps += 1
7        display.show(steps)

Step 3: Improve it

• Modify the code so it shows your current step count when you press a button.
• If you find that the code only counts every other step, modify the code to multiply the ‘steps’ variable by two when it’s displayed.
• Measure the length of your average stride and get your 娇花难养 to multiply this by the number of steps to calculate the distance you’ve walked.
