Circuit connection
Sample Code
int val;
int ledpin=13;
void setup()
{
Serial.begin(9600);
pinMode(ledpin,OUTPUT);
} void loop()
{ val=Serial.read();
if(val=='a')
{
digitalWrite(ledpin,HIGH);
delay(250);
digitalWrite(ledpin,LOW);
delay(250);
Serial.println("keyestudio");
}
}
Result
Open APP HC-COM, click search device, select the device, device is connected; the LED on the Bluetooth module is on. Enter “a” in HC-COM, click send, Bluetooth APP will display keyestudio. Every time HC-COM sends an “a”, the Pin13 LED on the main board blinks once.
