Can't Receive data from Arduino to MIT inventor app
问题
我正在为学校的物联网项目工作，但我在使用蓝牙模块将数据从Arduino发送到我的MIT应用程序时遇到问题。任何帮助将不胜感激。
char Incoming_value = 0;
void setup()
{
Serial.begin(9600);
pinMode(12, OUTPUT);
}
void loop()
{
if(Serial.available() > 0)
{
Incoming_value = Serial.read();
Serial.print(Incoming_value);
Serial.print("\n");
if(Incoming_value == '1'){
digitalWrite(12, HIGH);
delay(10000);
Serial.println("5");
}
}
}

if you are connecting a Bluetooth module to the arduino board, use SoftwareSerial.
here is a working example :
#include <SoftwareSerial.h>
SoftwareSerial btm(3, 2); // pin D3 and pin D2 as Rx and Tx
char c;
void setup() {
btm.begin(9600);
Serial.begin(9600);
}
void loop() {
if (btm.available() > 0) {
while (btm.available() > 0) {
c = btm.read();
Serial.print(c);
}
}
}
