Premetto che sono totalmente ignorante da questo punto di vista, in quanto ho fatto solo pratica con dei servizi online. Appunto oggi ho iniziato a fare il circuito base per accendere un led e, al momento del caricamento su scheda, sopo una verifica andata a buon fine, mi dà quest'errore.
Ho arduino UNO.
