Caute


Uz aj ja som hrdim vlastnnikom Arduina.Obraciam sa na vas.Nevedel by mi niekdo pomoct spravit podmienku?Moja predstava je ak v bojleru 1 bude teplota 60 c nezapinaj rele ak bude viac ako 60 zapny.Pripojene mam 2x DS18B20.Dakujem

V cem je problem ? Pouzij google

... nahore pridat ...

Kód: Vybrat vše

const int LED = 13;
const int RELE = 10;

v setupu pridat ...

Kód: Vybrat vše

pinMode(RELE, OUTPUT);

A kod by mel byt ...

Kód: Vybrat vše

if ((tempC > 60.00) && (deviceAddress == "insideThermometer"))  // podmienka na zopnutie rele 
{
digitalWrite(LED, HIGH);
digitalWrite(RELE, HIGH);
}
else
{ 
digitalWrite(LED, LOW);
digitalWrite(RELE, LOW);
}

... s tim, ze na PINu 13 tezko neco das, je tam natvrdo LEDka (vetsinou) ... takze pouzit 13 jako indikaci sepnuti rele ... a na sepnuti rele pouzit jiny pin, napsano je to pro pin 10.

A pro uplnost tady mas navod jak pripojit 5V rele k arduinu ... Tim rele muzes ovladat treba stykac a tak ...

Rele - napriklad ...

Dakujem.Preberal som to aj na inom fore a spravil som to takto.Teraz riesim grafiku na lcd.Nechce mi to zobrazit na cely lcd aj ked mam nastavene 84x48 rozlisenie.Vedel by mi niekdo poradit?

Kód: Vybrat vše

delay(500);
  sensors.requestTemperatures();
  ...
  if (sensors.getTempC(insideThermometer)>70.0 && sensors.getTempC(outsideThermometer)<75.0) digitalWrite(cerpadlo, HIGH);
  if (sensors.getTempC(insideThermometer)<60.0 || sensors.getTempC(outsideThermometer)>75.0) digitalWrite(cerpadlo, LOW);

neznám ten nokia LCD, ale někdy je potřeba buďto v parametru volání knihovny zadat ty, nebo rozlišení, nebo to případně upravit v knihovně (já si musím upravovat nastavení z 2x16 na 4x20 display...)

Tu je ta knihovna.Hladal som co by sa v nej malo zmenit ale nenasiel som.Vedel by si sa mi nato pozriet?Ked som skusal tento program tak to fungovalo na celom.Pridavam odkaz.
