Navigate to the MicroPython editor https://python.microbit.org/v/3. If you already have it open, then use that existing window or tab.
Connect your micro:bit using the instructions on the previous page
Enter the following code into the editor

from microbit import *


def motor_left(speed, direction):
    buf = bytearray(3)
    buf[0] = 0x00
    buf[1] = direction
    buf[2] = speed
    i2c.write(0x10, buf)


def motor_right(speed, direction):
    buf = bytearray(3)
    buf[0] = 0x02
    buf[1] = direction
    buf[2] = speed
    i2c.write(0x10, buf)


i2c.init()

while True:
    left_line = pin13.read_digital()
    right_line = pin14.read_digital()

    sleep(10)

Flash the code to your micro:bit.

If you get stuck ask a peer or your teacher for help!
