Program Arduino : Lampu Disko Led

Tujuan di sini adalah dengan menggunakan A / D converter pada Arduino untuk membaca suara input dan menerangi satu set LED untuk mencerminkan tingkat volume suara. LED dikendalikan dari pin Digital 3, 4, 5,6. Mereka diaktifkan berdasarkan apa tingkat input dari Analog 0 pin, yang terhubung ke jack headphone.

// LED light dance

#define soundpin 8 // reads the power from the light sensor from Analog input 0
#define LED1 3 // 4 Leds LED's on Digital output pins 3,4,5,6
#define LED2 4
#define LED3 5
#define LED4 6

int sound;

void setup()
{
// initialize the serial communications:
Serial.begin(9600);

// Provide power by using the analog inputs as normal digital pins.
pinMode(soundpin, INPUT);
pinMode(LED1, OUTPUT);
pinMode(LED2, OUTPUT);
pinMode(LED3, OUTPUT);
pinMode(LED4, OUTPUT);
}
void loop()
{
sound=analogRead(soundpin); // this samples the sound constantly
if((sound)>200)
{
digitalWrite(LED1,HIGH); // set the LEDs on
digitalWrite(LED2,HIGH);
digitalWrite(LED3,HIGH);
digitalWrite(LED4,HIGH);
}
else if((sound)>150)
{
digitalWrite(LED1,HIGH); // set the LED on
digitalWrite(LED2,HIGH);
digitalWrite(LED3,HIGH);
digitalWrite(LED4,LOW); // set the LED off
}
else if(sound>100)
{
digitalWrite(LED1,HIGH); // set the LED on
digitalWrite(LED2,HIGH);
digitalWrite(LED3,LOW); // set the LED off
digitalWrite(LED4,LOW);
}
else if(sound>50)
{
digitalWrite(LED1,HIGH); // set the LED on
digitalWrite(LED2,LOW); // set the LED off
digitalWrite(LED3,LOW);
digitalWrite(LED4,LOW);
}
else
{
digitalWrite(LED1,LOW); // set the LEDs off
digitalWrite(LED2,LOW);
digitalWrite(LED3,LOW);
digitalWrite(LED4,LOW);
}

Serial.println(soundpin); //output for serial monitor

delay(25); // And a shot delay
}
