Bu dersimizde bir platformu mause ile 2 eksen (sağ - sol ve yukarı - aşağı) hareket ettirmeyi öğreneceğiz. Platforma ben örnek olarak bir kaç tane led bağladım. Led yerine kamera ya da projektör gibi başka metaryeller bağlayarak bu metaryalleri 2 eksen kontrol edebilirsiniz. PC arayüzü olarak processingi kullanacağız. İhtiyaç duyulması halinde konuya ait dosyaları orjinal konu (https://temrinlerim.org/index.php?topic=225.0) ekinden (üyelik gerektirir)indirebilirsiniz.
