Okay both answers where really great…
i just cant get my head around this part of the code
{
digitalWrite(soilPower, HIGH);//turn D7 "On"
delay(10);//wait 10 milliseconds
val = analogRead(soilPin);//Read the SIG value form sensor
digitalWrite(soilPower, LOW);//turn D7 "Off"
return val;//send current moisture value
}
i want to check if i can rewrite this without the delay… maybe make it a void?
I don’t think a delay of 10 milliseconds will give you any problems. Especially if you are only reading the sensor every couple of seconds.
The other option is to use a timeout
digitalWrite(soilPower, HIGH);//turn D7 "On"
timer.setTimeout(10L, []() { // Lambda Timer Function
val = analogRead(soilPin);//Read the SIG value form sensor
digitalWrite(soilPower, LOW);//turn D7 "Off"
return val;//send current moisture value
}); // END
problem is there will be minimal of 4 soil sensors working on the shield… so 4 times the delays? plus my control of the relays should keep working to?
then go with option 2
will that not interfere with the connection to the blynk local server and such?
No it is non-blocking.
It is a very useful function, You should keep it saved for future use. Works with both setTimeout (run once), and setInterval (run continuously)
okay great…
would that interfere with the timer in my second code? (the one starting with UnoCorn add?

because there is allready a timer and timer.run in this code should i call one of them timer2.run? or something simular… ??
No, one instance of Blynk timer can support 16 individual timers.
Pete.
great 
and how do i make a difference between the different timers in code then?
the name? or how?
What is it that you’re trying to achieve?
If you just want to set-up some timers that do things every so often then there no reason to identify them, just do them like this…
timer.setInterval(60000L,function1); //call function 1 every 60 sec
timer.setInterval(2000L,function2); //call function 2 every 2 sec
If you need to delete or start/stop a timer then you do this by obtaining the timer ID and referencing this. Is this something you need to do?
Pete.
When i try your part of code
digitalWrite(soilPower, HIGH);//turn D7 "On"
timer.setTimeout(10L, []() { // Lambda Timer Function
val = analogRead(soilPin);//Read the SIG value form sensor
digitalWrite(soilPower, LOW);//turn D7 "Off"
return val;//send current moisture value
}); // END
i get this error?
exit status 1
expected ‘)’ before ‘}’ token
or when i try ) before } and then ;
i get this error?
exit status 1
expected primary-expression before ‘)’ token
post the whole function. It could be a missing ) or } elsewhere
and eventualy this?
invalid user-defined conversion from ‘myTimerEvent()::__lambda0’ to ‘timer_callback {aka void (*)()}’ [-fpermissive]
What?

}You need a closing bracket on the myTimerEvent function.
Plus I would probably ditch the return, and just use the global variable.

ah okay great… THANKS i’ll try it asap
Okay great that worked 
(the second time haha)
how would you use a global variant here?
i would like to use a virtual pin so i can it working on my Blynk local server and app on phone…
