primo approccio arduino

Inviato

ho acquistato arduino mega ma non so da dove cominciare. Ho caricato alcuni

esempi e ho capito il loro funzionamento. ho provato a modificare il progetto blink, volendo realizzare l'uscita 13 con un tempo on-off e l'uscita 12 con un secondo tempo on-off ma il risultato non e quello voluto. i due led al variare dei tempi vorrei che lampeggiassero indipendentemente fra loro. chi puo aiutarmi vi posto lo sketch

/* far lampeggiare 2 led */

 

int led1 = 13;

int led2 = 12;

void setup() {

 

pinMode(led1, OUTPUT);

pinMode(led2, OUTPUT);

}

 

void loop() {

digitalWrite(led1, HIGH);

delay(1000);

digitalWrite(led1, LOW);

delay(1000);

 

digitalWrite(led2, HIGH);

delay(1000);

digitalWrite(led2, LOW);

delay(1000);

}

Ciao :)

Sono nuovo nel forum ma ti posto un mio vecchio codice a 5 Led che facevano la "ola" con arduino 1 + ethernet shield

Se rielabori il codice , togliendo quello in eccesso relativo alla ethernet shield , ti tornerà utile credo!

A me per lo meno funzionava e ci ho messo una vita a scriverlo!
