Crazy timer on my sketch

[Tmaster]

hello . i'm finishing an second version from my water irrigation(1 valve control) and i have an issue with one of the timers that i can't understand.

its set for 1 hour,but never reach 1 hour, sometimes 47minutes ,other times 5 minutes.... annoying.

Can anyone understand this ? i'm too limited on programming :s

this is the crazy timer that i talk about:
this timer close the valv after 3600second(1hour) but won't work..

  unsigned long nowMillis = millis();
    
   if ((timer==true) && (nowMillis - startMillis >= VALVE_TIME))          
    {
      startMillis =  nowMillis ;
       VALV1_OFF();
       timer==false;

@tmaster the debug log will probably give good insight to why the node reacts early.

If you use the auto-formatting feature in the Arduino IDE, it will be much easier to follow the code.

@mfalkvidd said in Crazy timer on my sketch:

i just discovered the auto-formatting right now :)

About debug (mydebug) just reacts as normal,everything as should, but in shorter time... less 70-80% of the time most the times. Tomorrow i will get the arduino that its watering right know and change the code a bit..try some "while" instead of "if" or hammering it ;)

[mfalkvidd]

@tmaster the sketch has a few

timer==false;

that probably should be

timer=false;

[Tmaster]

Nice catch! i didn´t see that . thank you

[Tmaster]

@mfalkvidd that was the problem! I correct the code and timers are working perfect now. I will post the skematic and code this night on projects for if someone want to use it . Very handy on summer for water some vegetables like i do. It's a very simple build.

@tmaster great work!
