ok, i not know your project status,
but i think it’s worth to have a easy
TOGGLE button code ready.

// Basic Button Example / TOGGLE Version
//_________________________________________________________________ SETUP
void setup() {
  size(200, 200);
}

//_________________________________________________________________ DRAW
void draw() {
  background(200, 200, 0);
  myButton();
}

//_________________________________________________________________ MOUSE pressed function
void mousePressed() {
  left_mouse_click_button();
}

//_________________________________________________________________ YOUR code if button pressed
void user_on_button_click() {
  bV = ! bV;                                    // TOGGLE
  println("button PV "+bV);
  println("?what you want me to do now?");
}

//_________________________________________________________________ BUTTON ?TAB?
int bx=20, by=170, bw=60, bh=20;                // button rectangle settings X,Y,W,H
int bts=15;                                     // button text size
color bs  = color(0, 50, 150);                  // stroke 
color bf0 = color(0, 0, 200);                   // PV fill STOP 
color bf1 = color(0, 200, 0);                   // PV fill RUN
color cshow = bf0;                              // selected PV color
color bt  = color(200, 200, 0);                 // text
boolean benable=true;  // false;                // use button?
boolean bV = false;    // true;                 // button status                       
String bT0 = "START";                           // SP Text
String bT1 = "STOP";                            // SP Text
String tshow = "";                              // selected SP text temp

void myButton() {
  if (benable) {
    push();
    stroke(bs);
    strokeWeight(2);
    cshow = ( bV) ? bf1 : bf0;
    fill(cshow);                                 // same   if ( bV ) fill(bf1); else fill(bf0);
    rect(bx, by, bw, bh);
    fill(bt);
    textSize(bts);
    textAlign(CENTER);
    tshow = ( bV ) ? bT1 : bT0;                  // same    if ( bV ) tshow = bT1; else tshow = bT0;
    text(tshow, bx+bw/2, by+bh/2+bts/2);
    pop();
  }
}

//_________________________________________________________________ mouse click left on button
void left_mouse_click_button() {
  if (mouseButton == LEFT && overRect(bx, by, bw, bh) && benable ) user_on_button_click();
}

//_________________________________________________________________ mouse over rectangle yes/no
boolean overRect(int rx, int ry, int rwidth, int rheight) {
  if (mouseX >= rx && mouseX <= rx+rwidth   && 
    mouseY >= ry && mouseY <= ry+rheight)  return true;
  return false;
}
