## MicroPython 101 Lesson Plan

### Introduction

Get ready to exercise your body and mind! In this lesson, students will learn how to program their micro:bit into a helpful exercise tool that can track footsteps and time. Additionally, they'll learn how to display a clock timer animation. Note: The Pedometer (step counter) and Stopwatch projects from this lesson are intended to be used with a battery pack for the micro:bit.

### New Code

• accelerometer.get_x():This is an accelerometer function that returns the acceleration of an object moving horizontally (left and right).
• accelerometer.get_y(): This is an accelerometer function that returns the acceleration of an object moving vertically (up and down).
• accelerometer.get_z(): This is an accelerometer function that returns the acceleration of an object that's moving with depth (in the z-direction).
• display.clear(): This is a function that clears all images and doesn't show anything on the micro:bit.

### Vocabulary

• Pedometer : A device that detects the number of footsteps taken
• Stopwatch : A device that keeps track of time passed and has as a start/stop timer

### Objectives

Students will...

• Use the micro:bit to run coding examples
• Apply coding concepts to create Pedometer and Stopwatch projects

### Materials

• micro:bit device (recommended 1 per student)
• USB cable
• Computers, laptops, or Chromebooks (1 per student) with student account access to Tynker.com
• Optional: Battery pack
• Optional: Tape, string, or safety pin to wear the micro:bit on clothing or shoes

### Warm-Up(5 minutes)

• Tell students that the micro:bit has a built-in accelerometer that detects motions such as shaking and tilting. Can anyone think of a situation when someone would want to use the device?
• Explain that an accelerometer is often used in exercise to keep track of how many steps someone has walked. Can anyone think of other devices that use an accelerometer?

### Activities(45 minutes)

Facilitate as students complete all Track and Field modules on their own:
1. Track and Field (Document)

• Students will read a short document that introduces the lesson. They'll learn that today's activities include using the micro:bit's built-in accelerometer and time functions to create Pedometer (step counter) and Stopwatch projects.
• Optional: Ask if anyone has used a pedometer before.
• Students will learn that in this lesson, they'll build their own pedometer and stopwatch!
• Explain that a pedometer detects steps, whereas a stopwatch keeps track of time.

2. Project 1: Pedometer (DIY)

• In this module, students will learn how the micro:bit can detect and show acceleration measurements in three different directions.
• Make sure students know the difference between the X,Y, and Z-axes relative to their movement:
• X-axis: Horizontal (left-right) movement
• Y-axis: Vertical (up-down) movement
• Z-axis: Represents depth
• Try It Out! Display Accelerometer Values
• In this activity, students are encouraged to experiment with their code to get either Y or Z axis values.
• Here's a list of the different functions students can use:

• Coding Challenge, Step 1: Detecting Footsteps
• To solve this challenge, students need to program their micro:bit to detect footsteps.
• Make sure they read the requirements carefully:

• If students are struggling, ask them to read the comments and determine what function they should use. For example, the "#sleep for a bit" comment indicates that the student should use a sleep() function.
• Tell students that they'll expand on this project in the next module.

3. Counting Steps (DIY)

• Coding Challenge, Step 2: Counting the Steps
• Students will expand on their previous project by programming the micro:bit to track and display the user's total number of footsteps taken.
• Remind students that in Python, the += operator adds to the variable.
• Give a hint: Tell students to create a variable called steps and assign it a value of 0. They'll also need to display the steps variable using the display.scroll() function.

4. Gearing Up (DIY)

• This module instructs students to experiment with their code as they test and debug their pedometer program.
• Is the micro:bit falling off the student's clothing or shoes? Ask them to put the micro:bit inside their pocket or hold it in their hand.
• Is the micro:bit adding too many steps? Try increasing the value that compares the Y-axis. For example, if the value is set to "1500", try setting it to "1600":

• Is the micro:bit not counting enough steps? Try decreasing the value that compares the Y-axis. For example, if the value was set to "1500," try setting it to "1400":

5. Project 2: Stopwatch

• In this module, students will learn how to display and record time using their micro:bit.
• Explain to students that the running_time() function will return how much time has passed using milliseconds--not seconds.
• Step 1: Starting the Timer
• This section is mostly blank. Make sure students read the comments, coding tips, and criteria carefully.
• Give a hint: Tell students to use a while not loop. Also make sure they're using the correct syntax for button A:

• Tell students that they'll expand on this project in the next module

6. Finishing Touches (DIY)

• Coding Challenge, Step 2: Final Touches
• Students will expand on their previous project by programming the micro:bit to show the final time.
• Give a hint: Tell students to use a display.show() function and include four parameters (i.e., image, wait, loop, delay).

7. Timing It (DIY)

• This module instructs students to experiment with their code as they test and debug their stopwatch program.
• Encourage students to compare the accuracy of their stopwatch to a timer on a phone or stopwatch. Which is more accurate?
• Are students struggling to convert milliseconds to seconds? Ask them how many milliseconds are in one second. (Answer: 1000). Next, tell them to divide their final_time by 1000. Part of their solution might look like this:

8. Review

• This module reviews the following:
• The accelerometer.get_x() function returns the acceleration of an object moving horizontally (left and right).
• The accelerometer.get_y() function returns the acceleration of an object moving vertically (up and down).
• The accelerometer.get_z() function returns the acceleration of an object moving with depth.

9. Quiz (Multiple-choice)

• Students will be asked 5 quiz questions to review concepts from this lesson.

### Extended Activities(10 minutes)

• What's the difference between a pedometer and stopwatch? (Answer: A pedometer detects steps, whereas a stopwatch keeps track of time.)
• If your pedometer is adding too many steps, should you increase or decrease the value that compares the Y-axis? (Answer: Increase.)
• How can using a pedometer help a person live a healthier lifestyle? (Answer: It can make them more aware of how inactive or active they are. They can also establish goals that challenge them to take a certain number of steps a day.)
