thanks so much ... but please where is the loop() called
ReplyDeletesorry i didn't see your comment before it was hidden .So replying just now. the Loop automatically runs over and over after the setup function which runs only once after the arduino is powered up or is reset . Setup > Loop then everything happens in the Loop
Deletesalve seus nerds! to fazendo uma grow tbm acabei passando pelo projeto de voces queria ajudar, como trombamos?
ReplyDeleteEnglish Please. I have translated your comment and what i understood was that you need help with something.I don't know what problem are you having ?
DeleteGreat post.Thanks for sharing this article with us.Keep posting!!!
