Would this do what you want (add it right above k++)?

let index = k;
buttons[k].button.mousePressed(()=>{
    input.push(index);
});

When I copy-paste it there this massage comes up in the console:

TypeError: buttons[k].button is undefined (sketch: line 18)

Sorry, my bad. I changes something in the class as well: a getter to the button.

The class now returns a reference to the HTML button by means of the getter. that is used to attached the mousePressed to the button.
