2.2. Samples

2.3. Sample 1: Drive the car at a full speed.

from microbit import *
from TPBot import *

tp = TPBOT()
tp.set_motors_speed(100,100)

2.4. Result

The speed of the left and right wheels is at 100, the car moves forward at the full speed.

2.5. Sample 2: Turn the headlights on in random colors

from microbit import *
from TPBot import *
import random

tp = TPBOT()

while True:
    R = random.randint(0,255);
    G = random.randint(0,255);
    B = random.randint(0,255);
    tp.set_car_light(R,G,B)
    sleep(500)

2.6. Result

The headlights light up in different colours at random.

2.7. Sample 3: Obstacles avoidance

from microbit import *
from TPBot import *

tp = TPBOT()
while True:
    i = tp.get_distance(0)
    if i>3 and i<30:
        tp.set_motors_speed(-50, 50)
        sleep(500)
    else:
        tp.set_motors_speed(50, 50)

2.8. Result

The TPBot turns its direction once it detects any obstacle ahead of it.

2.10. Result

The TPBot drives along with the black line.

2.11. Sample 5: Control the servo

from microbit import *
from TPBot import *

tp = TPBOT()
while True:
    tp.set_servo(1,180)
    sleep(1000)
    tp.set_servo(1,0)
    sleep(1000)

2.12. Result

  • The servo connecting to S1 continues driving back and forth.
