3. Case 01: Move Forward or Reverse#

3.1. Introduction#

Use the A and B buttons on the Pico:ed to control the Cutebot to complete the basic forward and backward actions.

3.2. Programming Preparation#

Please refer to: Preparing the Programming Environment

Sample code :#

from picoed import *
from cutebot import *

# Create a sample for Cutebot category
cutebot = Cutebot()    

# While true, detect whether the A/B button is pressed, control the cutebot to move forward or backward
while True:
    if button_a.is_pressed():
        cutebot.set_speed(50,50)
    if button_b.is_pressed():
        cutebot.set_speed(-50,-50)

Code details#

  1. Import the modules that we need: cutebot module contains classes and functions that operate on the Cutebot smart car, and picoed module contains functions that operate on keys A\B.

from picoed import *
from cutebot import *
  1. Create a sample for Cutebot category

cutebot = Cutebot()
  1. While true, detect whether the A/B button is pressed, control the cutebot to move forward or backward.

while True:
    if button_a.is_pressed():
        cutebot.set_speed(50,50)
    if button_b.is_pressed():
        cutebot.set_speed(-50,-50)

3.3. Results#

After button A is pressed, the car moves forward at its full speed.

After button B is pressed, the car reverses at its full speed.

3.4. Exploration#

How to program the car to stop moving after pressing the A and B buttons at the same time?
