Na het uploaden van de code, hebt de eerste keer dat u de schets uitvoert u de tijd in te stellen. Uncomment deze lijn van code hier:
<p>//setRTCTime();</p>
Volgende huidige datum en tijd instellen op de volgende functie.
<p>void setRTCTime()<br>{ DateTime dt(2015, 8, 27, 9, 35, 30, 4); // Year, Month, Day, Hour, Minutes, Seconds, Day of Week rtc.setDateTime(dt); //Adjust date-time as defined 'dt' above }</p> Na het instellen van de tijd, uploaden van de schets en het eenmalig uit te voeren.
De lijn vervolgens de sets te commentariëren de tijd en updload de schets nogmaals.
setRTCTime();
Het programma kan nu, tijd met de ingesloten batterij jarenlang houden!
Geniet van uw kleur Real Time Clock!
