Sir yes sir!
Well I reconfigured the wires and still, it's not working.
Turns out I declared the analog value variables as 8bit integers...
But after rewriting the code, i get the next values:
UP: X is 12 ; Y is 510.
DOWN: X is 682 ; Y is 603.
LEFT: X is 570 ; Y is 22.
RIGHT X is 572 ; Y is 684.
Guess the right choice right now is to get different transistors, or just get an analog multiplexer.
