How To Use the micro:bit Python SDK

Driving

Drive with Heading

from microbit import sleep
from sphero import RVRDrive, RVRPower

# wait for RVR to turn on
RVRPower.wake()
sleep(2000)

# drive forward
count = 0
while count < 15:
    RVRDrive.drive(60, 0)
    sleep(200)
    count += 1

# drive to the right
count = 0
while count < 15:
    RVRDrive.drive(60, 90)
    sleep(200)
    count += 1

# drive back
count = 0
while count < 15:
    RVRDrive.drive(60, 180)
    sleep(200)
    count += 1

# drive to the left
count = 0
while count < 15:
    RVRDrive.drive(60, 270)
    sleep(200)
    count += 1

# stop driving
RVRDrive.stop(270)

Set Raw Motors

from microbit import sleep
from sphero import RVRDrive, RawMotorModes, RVRPower


# wait for RVR to turn on
RVRPower.wake()
sleep(2000)

# drive forward with speed 60
count = 0
while count < 15:
    RVRDrive.set_raw_motors(RawMotorModes.FORWARD, 60, RawMotorModes.FORWARD, 60)
    sleep(200)
    count += 1

# stop and wait 1 second
RVRDrive.set_raw_motors(RawMotorModes.OFF, 0, RawMotorModes.OFF, 0)
sleep(1000)

# drive backward with speed 60
count = 0
while count < 15:
    RVRDrive.set_raw_motors(RawMotorModes.BACKWARD, 60, RawMotorModes.BACKWARD, 60)
    sleep(200)
    count += 1

# stop and wait 1 second
RVRDrive.set_raw_motors(RawMotorModes.OFF, 0, RawMotorModes.OFF, 0)
sleep(1000)

# drive forward with speed 80 on the left motor and speed 40 on the right motor
count = 0
while count < 20:
    RVRDrive.set_raw_motors(RawMotorModes.FORWARD, 80, RawMotorModes.FORWARD, 40)
    sleep(200)
    count += 1

# stop and wait 1 second
RVRDrive.set_raw_motors(RawMotorModes.OFF, 0, RawMotorModes.OFF, 0)
sleep(1000)

# drive forward with speed 40 on the left motor and speed 80 on the right motor
count = 0
while count < 20:
    RVRDrive.set_raw_motors(RawMotorModes.FORWARD, 40, RawMotorModes.FORWARD, 80)
    sleep(200)
    count += 1

# stop
RVRDrive.set_raw_motors(RawMotorModes.OFF, 0, RawMotorModes.OFF, 0)

LEDs

Set LEDs

from microbit import sleep
from sphero import RVRLed, LEDs, RVRPower


# wait for RVR to turn on
RVRPower.wake()
sleep(2000)

# turn all LEDs off and wait 2 seconds
RVRLed.set_all_leds(0, 0, 0)
sleep(2000)

while True:
    # turn all LEDS off
    RVRLed.set_all_leds(0, 0, 0)

    # set headlights to red
    RVRLed.set_rgb_led_by_index(LEDs.RIGHT_HEADLIGHT, 255, 0, 0)
    RVRLed.set_rgb_led_by_index(LEDs.LEFT_HEADLIGHT, 255, 0, 0)

    # wait 1 second
    sleep(1000)

    # set headlights to yellow
    RVRLed.set_rgb_led_by_index(LEDs.RIGHT_HEADLIGHT, 255, 255, 0)
    RVRLed.set_rgb_led_by_index(LEDs.LEFT_HEADLIGHT, 255, 255, 0)

    # wait 1 second
    sleep(1000)

    # set headlights to green
    RVRLed.set_rgb_led_by_index(LEDs.RIGHT_HEADLIGHT, 0, 255, 0)
    RVRLed.set_rgb_led_by_index(LEDs.LEFT_HEADLIGHT, 0, 255, 0)

    # wait 1 second
    sleep(1000)

    # set headlights to blue
    RVRLed.set_rgb_led_by_index(LEDs.RIGHT_HEADLIGHT, 0, 0, 255)
    RVRLed.set_rgb_led_by_index(LEDs.LEFT_HEADLIGHT, 0, 0, 255)

    # wait one second
    sleep(1000)

    # set all LEDs to white and wait 2 seconds
    RVRLed.set_all_leds(255, 255, 255)
    sleep(2000)
