bunogenrinho:
I send the code to arduino so i can start to use. The first time i use the bottons to make it rotate after 1 minute and it works, but when i do the same thing again it doesn't rotate. I only send it once to arduino
This is very confusing.
When you say "send the code" do you mean that you "upload the program".
I normally interpret the word "send" to mean sending data to a running program - perhaps by typing numbers or characters into the Arduino Serial Monitor.
Then you say "first time i use the bottons" but you have not told exactly what buttons you pressed and in what order.
