Arduino Lcd Keypad ile Oyun Yapımı

Herkese iyi çalışmalar arduino keypad ile bir proje yapalım 🙂 projemiz bir oyun projesi olucak oldukça kolay ve eglenceli bir proje

Neden Lcd Keypad ?

lcd keypad kullanmamızın amacı kablo bağlantılarından bizi kurtarması olacaktır. Ve bize bir gamepad havası verecektir.  Peki lcd kullanamazmıyız kullanırız hatta hiç bir kod değişimi yapmadan sadece 4 adet daha buton eklememiz gerekicek .

Lcd keypad ı mızı arduinomuza taktıktan sonra projemizin bağlantıları tamamdır.

şimdi kod kısmına geçelim 🙂

Kullanılan Mazemeler ve Fiyatları :

Arduino Uno                 (20 TL)

Kodu Arduinomuza yükledikten sonra işlem tamamdır hepinize iyi oyunlar dilerim 🙂
