Buzzer on using potentiometer
Arduino Uno - 01
Breadboard - 01
330 Ohm Resistors - 01
10K Potentiometer - 01
Jumper wires
int buzzer = 13; // Buzzer connected to digital pin No 13
int potentio = A0; // potentiometer connected to digital pin No 2
int ANALOG_THRESHOLD = 500; // Analog Threshold (This value can change)
void setup(){ // Function is called when sketch start
pinMode(buzzer, OUTPUT); // Buzzer is an Output
pinMode (potentio,INPUT); // potentiometer is an Input
}
void loop(){ // Run continuously
int analogValue = analogRead(potentio); // Read the analog pin value
if(analogValue > ANALOG_THRESHOLD){ // if analog value more than THRESHOLD
tone(buzzer, 700); // Buzzer ON(This Value can change)
}
else{
noTone(buzzer); //*if Buzzer OFF
}
}
