Creating Something Unique

On this part of the lab I used a force-sensor in combination with a speaker to produce some sound. First, I had to decide what were the ranges my sensor was giving me, so I used the serial monitor. The results of the serial monitor were 140 and 0, 140 being the number when it had the most pressure on it and 0 for the least. Having this numbers I divided 140 into 3, to create 3 different ranges;The first range being a number in between 19 and 47, the second one between 46 and 93 and the third 92 and over. Respectively a note was given to each one of these ranges, C4, D4 and E4. The result was, a system that operates as the force sensor is pressed with different forces, to produce different melodic sounds.

This was the code done to obtain this result:

#include <Tone.h>
Tone mytone; // declare a tone name

void setup() {
// initialize the tone
mytone.begin(8);
mytone.play(NOTE_B3);
delay (500);
mytone.stop();
delay (500);
}

void loop()
{
int inVar = analogRead(0);// read the analog input
if((inVar>= 20) && (inVar<=46)) { //when the variable is in between 19 and 47
mytone.play(NOTE_C4);// play note C4
}

else if((inVar>= 47) && (inVar<=92)) {// when the variable is in between 46 and 93
mytone.play(NOTE_D4);//play note D4
}

else if(inVar>= 92) {//when the variable is 92 or over
mytone.play (NOTE_E4);//play note E4

}
if(inVar<19){
mytone.stop();
}
}
