Yararsız

Bu uygulama yerine farklı sitelerden daha detaylı bir şekilde yararlanıla bilir uygulama içeriği çok boş

Süper!!

Arduino hakkında o kadar uygulama denedim ancak bu kadar profunu görmedim. Çok faydalı olmuş emeğinize sağlık…

Helal be

Uygulama çok iyi başlangıç için biraz daha fazla ücretsiz proje olursa daha iyi olur ama zaten paralı versyonda çok ucuz
