HC-05蓝牙模块与Arduino通信测试

• 硬件

  • Arduino UNO
  • HC-05 Bluetooth module master/slave
  • ZS-040
  • 杜邦线若干
  • 有蓝牙适配器的PC一台

• 软件

  • Arduino IDE
  • application serial communicator

• 步骤

  • 接线

VCC --> 5V
GND --> GND
TX --> RX
RX --> TX

- 测试代码
  ```
#include <SoftwareSerial.h>
SoftwareSerial Conn(10, 11); //RX, TX
void setup() {
// put your setup code here, to run once:
Conn.begin(38400);
}
void loop() {
// put your main code here, to run repeatedly:
Conn.println("Test Transmission String.");
delay(600);
}

• 结果
