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.

Note: The above used APP is only compatible with Android system. You need to search BLE Scanner 4.0 to download app in APP store if your use iphone.
