hello. i am creating an arduino machine. it is talking to processing using the library standardFirmata(arduino). in this arduino there are three elements: two buttons and a joystick. a Pshape can be moved in the sketch with the joystick. the action of pressing the first button will stamp the Pshape on the sketch. these elements are working. now i want to add a second button, to change the Pshape with another different pshape( and then everytime i am pressing a button i want a third and a fourth phshape to appear instead of the first one … and so on and then starting againg with the first pshape in a loop) i dont know how to code this latter button.
this is my code
PShape rectangle;
PShape triangle;
PShape circle;
PShape s;
PShape n;
PShape iletter;
PShape e;
PShape o;
PShape u;
PShape v;

IntList cy = new IntList();

int ypos = 250;
