For this exercise we decided to mix a sound detector connected to Arduino with 8 LED systems.
We wanted to specify the information transmission capacity between the two systems.
To do this we decided to divide the sound into three categories; low, medium, high.
/* * Mantas Utka */int ledPin1= 13; //Adding the LED's and sensor.
int ledPin2= 12;
int ledPin3= 11;
int ledPin4= 10;
int ledPin5= 9;
int ledPin6= 8;
int ledPin7= 7;
int ledPin8= 6;
int sensorPin= A0; //The sensor selecting as Analog pin. The Analog Pin is better for projects as this one.
int val = 0;
void setup(){ pinMode(ledPin1, OUTPUT); //Selecting LEDs as outputs to push the results in LEDs of sound detector
pinMode(ledPin2, OUTPUT);
pinMode(ledPin3, OUTPUT);
pinMode(ledPin4, OUTPUT);
pinMode(ledPin5, OUTPUT);
pinMode(ledPin6, OUTPUT);
pinMode(ledPin7, OUTPUT);
pinMode(ledPin8, OUTPUT);
pinMode(sensorPin, INPUT); //Selecting the sensor as input to send results into Arduino
Serial.begin (9600);
}void loop (){
val =analogRead(sensorPin);
Serial.println (val); // when the sensor detects a signal, LED flashes
//1
if (val >= 127) {
digitalWrite(ledPin1, HIGH); //selecting the values of LEDs to flash by detecting values of sound sensor. }
else {
digitalWrite(ledPin1, LOW); }
//2
if (val >= 378) {
digitalWrite(ledPin2, HIGH); }
else {
digitalWrite(ledPin2, LOW); }
//3
if (val >= 505) {
digitalWrite(ledPin3, HIGH); }
else {
digitalWrite(ledPin3, LOW); }
//4
if (val >= 632) {
digitalWrite(ledPin4, HIGH); }
else {
digitalWrite(ledPin4, LOW); }
//5
if (val >= 759) {
digitalWrite(ledPin5, HIGH); }
else {
digitalWrite(ledPin5, LOW); }
//6
if (val >= 886) {
digitalWrite(ledPin6, HIGH); }
else {
digitalWrite(ledPin6, LOW); }
//7
if (val >= 980) {
digitalWrite(ledPin7, HIGH); }
else {
digitalWrite(ledPin7, LOW); }
//8
if (val >= 1000) { digitalWrite(ledPin8, HIGH); }
else {
digitalWrite(ledPin8, LOW); }}
