Arduino Bluetooth Light Control Code
------------------------------------
char command; // To store received Bluetooth commands
const int ledPin = 7; // Pin connected to the LED
void setup() {
pinMode(ledPin, OUTPUT);
digitalWrite(ledPin, HIGH); // LED OFF initially
Serial.begin(9600);
// Print your name once when Arduino starts
Serial.println("WELCOME ELECTRONICS WITH DHARMA");
Serial.println("Bluetooth Light Control Ready");
}
void loop() {
if (Serial.available()) {
command = Serial.read();
if (command == '1') {
digitalWrite(ledPin, LOW);
Serial.println("LED ON - ELECTRONICS WITH DHARMA");
}
else if (command == '0') {
digitalWrite(ledPin, HIGH);
Serial.println("LED OFF - ELECTRONICS WITH DHARMA");
}
}
}
