my project consists of two servos ,a distance sensor and a prossessing code the servos are ment to goto mouseX and mouseY which they do then the distance sensor is ment to send the distance to the prossessing and it creates a box at mouseX and mouseY and it coulor depends on how
far the distance is but it is geting weird distances which repeat so i am unsure of the problem
