树莓派小车绕8字python代码

以下是树莓派小车绕8字的Python代码示例：

import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BOARD)

# 定义左右轮引脚
left_motor_pin = [11, 12, 13, 15]
right_motor_pin = [16, 18, 22, 7]

# 设置引脚模式
for pin in left_motor_pin + right_motor_pin:
    GPIO.setup(pin, GPIO.OUT)

# 定义小车运动函数
def move(direction, running_time):
    if direction == 'forward':
        GPIO.output(left_motor_pin[0], True)
        GPIO.output(left_motor_pin[1], False)
        GPIO.output(right_motor_pin[0], True)
        GPIO.output(right_motor_pin[1], False)
    elif direction == 'backward':
        GPIO.output(left_motor_pin[0], False)
        GPIO.output(left_motor_pin[1], True)
        GPIO.output(right_motor_pin[0], False)
        GPIO.output(right_motor_pin[1], True)
    elif direction == 'turn_left':
        GPIO.output(left_motor_pin[0], False)
        GPIO.output(left_motor_pin[1], True)
        GPIO.output(right_motor_pin[0], True)
        GPIO.output(right_motor_pin[1], False)
    elif direction == 'turn_right':
        GPIO.output(left_motor_pin[0], True)
        GPIO.output(left_motor_pin[1], False)
        GPIO.output(right_motor_pin[0], False)
        GPIO.output(right_motor_pin[1], True)
    time.sleep(running_time)
    GPIO.output(left_motor_pin[0], False)
    GPIO.output(left_motor_pin[1], False)
    GPIO.output(right_motor_pin[0], False)
    GPIO.output(right_motor_pin[1], False)

# 绕8字运动
for i in range(4):
    move('forward', 1.5)
    move('turn_left', 0.5)
    move('forward', 1.5)
    move('turn_right', 0.5)

GPIO.cleanup()
