写一个Micropython+Thonny的esp32蓝牙控制小车的程序

好的，下面是一个 Micropython Thonny 的 esp32 蓝牙控制小车的程序示例：

import bluetooth
from machine import Pin
import time

# 蓝牙设备名称和地址
device_name = "ESP32_Car"
device_address = "AA:BB:CC:11:22:33"

# 初始化蓝牙连接
server_socket = bluetooth.BluetoothSocket(bluetooth.RFCOMM)
server_socket.bind((device_address, 1))
server_socket.listen(1)

# 控制小车的引脚
pin1 = Pin(2, Pin.OUT)
pin2 = Pin(4, Pin.OUT)
pin3 = Pin(16, Pin.OUT)
pin4 = Pin(17, Pin.OUT)

# 控制小车的函数
def forward():
    pin1.on()
    pin2.off()
    pin3.on()
    pin4.off()

def backward():
    pin1.off()
    pin2.on()
    pin3.off()
    pin4.on()

def left():
    pin1.off()
    pin2.on()
    pin3.on()
    pin4.off()

def right():
    pin1.on()
    pin2.off()
    pin3.off()
    pin4.on()

def stop():
    pin1.off()
    pin2.off()
    pin3.off()
    pin4.off()

# 等待客户端连接
print("等待客户端连接...")
client_socket, client_address = server_socket.accept()
print("已连接客户端：", client_address)

# 循环接收客户端消息并控制小车
while True:
    try:
        data = client_socket.recv(1024).decode().strip()
        if not data:
            print("客户端已关闭")
            break
        elif data == "F":
            forward()
        elif data == "B":
            backward()
        elif data == "L":
            left()
        elif data == "R":
            right()
        elif data == "S":
            stop()
        else:
            print("无效命令：", data)
    except Exception as e:
        print("发生异常：", e)

# 关闭蓝牙连接和引脚
client_socket.close()
server_socket.close()
pin1.off()
pin2.off()
pin3.off()
pin4.off()

希望这个程序能够帮到你。如果你有任何问题或需要更多帮助，可以继续问我哦。
