With the tilt direction display mentioned in the Did You Know? section on the previous page, your script can display a needle that either points up or down.
Example Script: display_tilt_direction_with_leds
- Enter, name, and save display_tilt_direction_with_leds.
- Click the Send to micro:bit button.
# display_tilt_direction_with_leds from microbit import * import math sleep(1000) while True: x = accelerometer.get_x() y = accelerometer.get_y() angle = round( math.degrees( math.atan2(y, x) ) ) needle = ( angle + 90 + 15 ) // 30 print("angle =", angle, ", needle =", needle) display.show(Image.ALL_CLOCKS[needle]) sleep(200)
- Check the results in the serial monitor.
- Try rotating and tilting your micro:bit in various directions, and verify that the display always points downward.
- Change the first plus sign in
needle = ( ( angle + 90 ) + 15 ) // 30
…to a minus sign:
needle = ( ( angle - 90 ) + 15 ) // 30
- Click Send to micro:bit to flash the modified script into the micro:bit.
- Try rotating and tilting your micro:bit in various directions again.
- Verify that the display always points upward.
