Story

Our teacher made us to make something. So, we thought and made this.

This cube is an instrument. This cube makes various sounds, when we turn the potentiometer.

Code

int Pot = A1;
int av;
int Switch = 5;
int SwitchState = 0;
int L7 = 6;
int L8 = 3;
int L9 = 2;
int L10 = 9;
int speaker = 8; // Breadboard 2
void setup() {
  Serial.begin(9600);
  pinMode (speaker, OUTPUT);
  pinMode (Switch, INPUT);
}
void loop() {
  av = analogRead(Pot);
  av = map(av, 0, 1023, 1, 5);
  Serial.print(av);
  Serial.println(SwitchState); 
  SwitchState = digitalRead(Switch);
   if(av == 1){
    digitalWrite(L7, HIGH);
    digitalWrite(L8, LOW);
    digitalWrite(L9, LOW);
    digitalWrite(L10, LOW);
  }else if(av == 2){
    digitalWrite(L7, LOW);
    digitalWrite(L8, HIGH);
    digitalWrite(L9, LOW);
    digitalWrite(L10, LOW);
  }
  else if(av == 3){
    digitalWrite(L7, LOW);
    digitalWrite(L8, LOW);
    digitalWrite(L9, HIGH);
    digitalWrite(L10, LOW);
  }
