Micro:bit Lesson 7 Reaction Timer Game

Specification Sheet

• Program Name: Reaction Timer Game
• Purpose: Simulate a reaction game where the user tilts the Micro:bit based on a displayed arrow.
• Features:
  • Displays random directional arrows (N, S, E, W).
  • Detects user tilt direction using the accelerometer.
  • Provides visual feedback with happy or sad faces.
• Inputs: Accelerometer tilt values.
• Outputs: Arrow display, happy/sad face feedback.
• Control Logic: Random direction selection, tilt detection, feedback display.

Pseudocode

Initialize a list of directions ["N", "S", "E", "W"]

Loop Forever:
    Randomly select a direction from the list

    If the direction is "N":
        Display an upward arrow
    Else if the direction is "S":
        Display a downward arrow
    Else if the direction is "E":
        Display a rightward arrow
    Else if the direction is "W":
        Display a leftward arrow

    Wait for 1 second

    If direction is "N" and accelerometer detects tilt upwards:
        Display a happy face
    Else if direction is "S" and accelerometer detects tilt downwards:
        Display a happy face
    Else if direction is "E" and accelerometer detects tilt to the right:
        Display a happy face
    Else if direction is "W" and accelerometer detects tilt to the left:
        Display a happy face
    Else:
        Display a sad face

    Wait for 2 seconds
    Clear the display
        

Purpose: You will be using the Micro:bit physical Hardware.

In this lesson, you will write a Python program to run on the micro:bit 
that will learn the Microbit Hardware.
Your video will be of the actual Micro:Bit hardware.
            
            You will drop off 5 files into Google Classroom:
            • Your files will be: (Remember the python program is dropped off first.)
                • PX_lastname_Direction.py (Python program)
                • PX_lastname_Direction.hex (Hex file for Microbit hardware)
                • PX_lastname_Direction.png (Screenshot)
                • PX_lastname_Direction.mp4 (Video running the program)
				• PX_lastname_Direction.mp4 (Video running the program on the micro:bit Hardware)

            
              Current Resources needed:
                 Check in and check out your Micro:Bit
                 Launch the Micro:Bit Python interpreter
                 At this time you will run your code.
                 Use the online Microbit but still download the hex file for hardware use.

            
                 If you do not understand this assignment,
                 ask Mr. Cusack and/or attend tutorials.
