Control Motor Rotation
Control two motors at the same time, and set their rotating direction and speed
Stop motor when button A is pressed
Control servo to rotate in certain angle.
There are also some block in Avandced->More which can be used to control servo
You can get more information about python programming of micro:bit on this web page: https://microbit-micropython.readthedocs.io/en/latest/index.html
We provide python codes for this module, you can download and have a try.
Unzip the demo code you download and open the file motor.py which is under the python directory with software mu.
Control servo to rotate in certain angle
Temp=angle/2+25 is the duty ratio, its range is 0~1023.
Motor1 moves forward, Motor2 moves backward, servo1 rotate 50 degrees, servo2 rotate 150 degrees.
