Lab: Building a Fidget Device#
Objective#
In this lab, you will design and build a fidget device using the BBC micro:bit. Your device should have at least five different input/output reactions.
Materials#
1 PC or Laptop
1 BBC micro:bit
1 Micro USB cable
Inputs#
Buttons
Capacitive touch logo
Accelerometer
Temperature sensor
Light sensor
Sound sensor
Compass
Outputs#
5x5 LED matrix
Buzzer
Instructions#
Setup: Connect your BBC micro:bit to your PC or laptop using the Micro USB cable.
Programming Environment: Open the MakeCode for micro:bit programming environment on your PC or laptop.
Design Your Fidget Device: Sketch out a design for your fidget device. Think about how you can incorporate the inputs and outputs in an interactive and fun way.
Code Your Device: Using the MakeCode editor, write code to control your device. Here are some ideas for input/output reactions:
When a button is pressed, display a pattern on the LED matrix.
When the device is shaken, make the buzzer sound.
When the light level changes, change the display on the LED matrix.
When a loud sound is detected, make the buzzer sound.
When the device is tilted, change the display on the LED matrix.
Test Your Device: After you’ve written your code, download it to your micro:bit and test your device. Make sure all the inputs and outputs are working as expected.
Document Your Work: Take pictures or videos of your device in action. Write a brief report (3-5 paragraphs) explaining your design process, how you coded your device, any challenges you faced, and how you overcame them.
Present Your Work: Prepare a short presentation to share your fidget device with the class. Demonstrate each input/output reaction and explain how you created it.
Reflection: Write a brief report explaining the logic behind your code and how it results in a fidget device with at least five input/output reactions.
