A bot kezdőpozíciója a ( x,y:511,511). Ha a botot az X tengelyen az egyik végétől a másikig mozgatjuk, az X értékek 0 és 1023 között változnak, és hasonló történik, ha az Y tengely mentén mozgatjuk. Ugyanezeken a vonalakon ezen értékek kombinációjából leolvasható a pálca pozíciója a felső félgömb bármely pontján.

Nézzük meg ezeket az értékeket soros porton!

Az érzékelőnek 4 tüskéje van. A VCC és a GND az Arduino 5V és GND pinjeire megy, a Trig és Echo pedig bármelyik digitális Arduino tüskéire. A Trig pin segítségével elküldjük az ultrahanghullámot az adóból, és az Echo pin segítségével hallgatjuk a visszavert jelet.

A szenzor adatlapja:
