My Problem is With Blynk
First Mode auto it work normal
Then i change Mode Manual it work well
When i change back to Auto it not work
if i make for only one sensor it work well but when use 3 same sensor with 3 motor it not work well
Arduino NodeMCU
Soil Moisture Sensor(i use Digital)
Arduino 4 Channel Relay Module
DC Pump Motor
Sensor1 (16) control Motor1 (14)
Sensor2 (05) control Motor2 (12)
Sensor3 (04) control Motor3 (13)
Well the code is a little tricky to follow but some things I noticed that MAY be causing your issue
Here you use V6 to initiate the auto and manual timers, but they never get turned off. So essentially they could both be running together. So when you are in auto mode it gets to the if statements in the manual function and most/all of them will not be true therefore the else statement will be executed.
Also, it seems that your Auto function has an extra set of brackets, and
is not contained within the first if statement as the other two are. Not sure if this was done on purpose.
And I am not sure of the point of creating a timer just to delete it 1 second later.
This will depend on what you are trying to accomplish. As you do not want both timers enabled at the same time, you will need to disable one while enabling the other.
Which is what I would expect with both the auto mode and manual mode functioning at the same time.
Just blindly following someone elses code is probably not the best idea. You need to understand why they are doing what they are doing, and determine if this is what you are trying to achieve. You need to understand what is going on in the code first.
I suggest you take some time to learn about programming and its basic functions, like if/else functions. YouTube and Google are a good place to start. You will also want to read about SimpleTimer and how to properly utilize its functions. SimpleTimer can be a very powerful tool, and is almost a MUST for BLYNK. You will also need to study the BLYNK DOCS, and make sure you understand the BLYNK functions/commands, how they relate to certain widgets and how/when to properly use them.
After all of that take another look at your code and try to fix the things mentioned in my first post. If you are still struggling, then post your “fixed” code and we (the BLYNK Community) will see if we can provide any guidance/support and get you on the right track.
Thank you so much i had learn many thing it work well
but went i go to Auto Back it slow a bit to trigger …
I put disable timer at V6 (the timer i dedclare 2 that for Auto and manual)
Correct me if i wrong …
Thank you

i see there had extra bracket at led 2 off…
ok i will change it thank you so much
Ok i had done complete code it work very well and perfect
