I coded a simple synth where
Pitch = sensor value * 2
But then I gave it a shot to make it more interesting.
I want to have 4 toggle-able pushbuttons which replace the "multiplier" with a variable multiplier.
This way, depending on what button was pressed last, the pitch is unique from the others.
I sort of left the coding at a cliffhanger.
Any help or advice at all really is appreciated.
//declare variables:
const int b1Pin = 3;
const int b2Pin = 4;
const int b3Pin = 5;
const int b4Pin = 6;
int varPin = analogRead(A0);
int button1 = digitalRead(b1Pin);
int button2 = digitalRead(b2Pin);
int button3 = digitalRead(b3Pin);
int button4 = digitalRead(b4Pin);
int lastButtonPressed = 1;
int currentButton = 1;
int buttonState = 0;
int lastButtonState = 0;
void setup(){}
void loop()
{
//Button input changes variable currentButton
if (button1 == HIGH)
{currentButton == 1;}
if (button2 == HIGH)
{currentButton == 2;}
if (button3 == HIGH)
{currentButton == 3;}
if (button4 == HIGH)
{currentButton == 4;}
if (currentButton != lastButtonPressed) //If new button isn't the same as last
{lastButtonPressed = currentButton;} //Change it to new value
int varPitch = map(varPin, 100, 1000, 100, 5000) * lastButtonPressed;
//Pitch will equal sensor value times the "button multiplier".
tone(7, varPitch); //Play it.
}
