It is a small game created by me.

You can play musics in this game ,pushing the buttons ,if you want a more light sound turn the potenciometer or a low frequency sound you just do the same.

Supplies

Arduino
Breadboard
jumpers
4x Push Buttons
10K potenciometer
piezo Buzzer
220 resistor
USB cable

Step 1: Wireing

Wire the components together like the schematic.

Step 2: The Code :

Put this code into the Arduino IDE and upload to the board.

#define A 2
#define B 3
#define C 4
#define D 5
#define TONE 9
void setup() {
  // put your setup code here, to run once:
pinMode(A,INPUT);
pinMode(B,INPUT);
pinMode(C,INPUT);
pinMode(D,INPUT);
pinMode(TONE,OUTPUT);
pinMode(A0,INPUT);
}
void loop() {
  // put your main code here, to run repeatedly:
while (digitalRead(A)==HIGH){
  tone(TONE,analogRead(A0));
}
while (digitalRead(B)==HIGH){
  tone(TONE,(analogRead(A0)+100));
}
while (digitalRead(C)==HIGH){
  tone(TONE,(analogRead(A0)+150));
}
while (digitalRead(D)==HIGH){
  tone(TONE,(analogRead(A0)+200));
}
noTone(TONE);
delay(100);
}
