Microbit-Python Course 6.9 Small fan

Learning goals:

This lesson learns to use the Python language to program the fan motor to turn. After pressing the A button, the fan starts to rotate and there is an animation of the fan turning on the dot matrix.

Code

from microbit import *
fun1 = Image("00990:90900:99999:00909:09900")
fun2 = Image("99009:09099:00900:99090:90099")
all_fun = [fun1, fun2]
while True:
    if button_a.is_pressed():
      while True:
          pin0.write_digital(1)
          display.show(all_fun, delay=100)
    else:
      display.show(Image.HEART)
      display.clear()

5. After the download is successful, we can see a heart on the micro:bit dot matrix, as shown in Figure 9-5. When the A button is pressed, the fan starts to rotate, and an animation of the fan rotation appears on the dot matrix, as shown in Figure 9- 6, 9-7.
