帮我写一个arduino UNO到esp32的串口通信代码

好的,我可以回答这个问题。以下是一个简单的 Arduino UNO 到 ESP32 的串口通信代码示例:
```
// 定义 Arduino UNO 的串口
SoftwareSerial mySerial(2, 3); // RX, TX
void setup() {
// 初始化串口
Serial.begin(960);
mySerial.begin(960);
}
void loop() {
// 从 Arduino UNO 的串口读取数据
if (mySerial.available()) {
char c = mySerial.read();
// 将数据发送到 ESP32 的串口
Serial.write(c);
}
// 从 ESP32 的串口读取数据
if (Serial.available()) {
char c = Serial.read();
// 将数据发送到 Arduino UNO 的串口
mySerial.write(c);
}
}
```
这个代码示例使用了 SoftwareSerial 库来定义 Arduino UNO 的串口,并在 `setup()` 函数中初始化了两个串口。在 `loop()` 函数中,我们不断地从 Arduino UNO 的串口读取数据,并将其发送到 ESP32 的串口;同时,我们也不断地从 ESP32 的串口读取数据,并将其发送到 Arduino UNO 的串口。这样,就实现了 Arduino UNO 和 ESP32 之间的串口通信。
