Test Tilts

Let's test tilts: level, left, right, toward, and away from you.

When you vary the tilt angle from left to right, the x-axis accelerometer measurement values vary accordingly.


When you vary the tilt angle from facing toward you to facing away from you, the y-axis accelerometer measurement values also vary accordingly.

Example script: test_tilts_intro

  • Enter this script and save it as test_tilts_intro.  
  • Flash the script into the micro:bit
# test_tilts_intro

from microbit import *

sleep(1000)

while True:
    x = accelerometer.get_x()
    y = accelerometer.get_y()
    
    print("x =", x, ", y =", y)
    
    sleep(750)
  • Open the terminal.
  • Take measurements as shown in the animation, recording the x and y values for each tilt angle in the table below the animation.
