Sevgili genç dostlarım,
Uzun süren bir çabadan sonra ,benim için zor olan engel algılayan robot araba yapmayı başardım.
Zar zor bu donanıma uyan Arduino platformunda çalışan programını da netten bulup,yükledim.
Araba çalıştı fakat otonom kendi kendine çalışan araba oldu.Ben bunu kızıl ötesi uzaktan kumandalı
hale nasıl getirebilirim bir türlü yapamadım çünkü, programlama bilgim yok, bu yüzden yardımlarınızı
bekliyorum.
Yazılımı şöyle:

Infra red kumandamın kodları ise şöyle

forward 0xFF629D
left 0xFF22DD
Right 0xFFC23D
Backward 0xFFA857
Okey 0xFF02FD

Uzaktan kumanda için hangi kodları ,nasıl yazılıma ekleyebileceğimi bana yazarsanız çok makbüle geçer.
Buda arabamın resmi ona birde ad koydum :)) Adı George.
