Help me with email notification

Need Help With My Project
1

I want my project only send a email notification when the status of the feeder is change base on fsr sensor, not looping. this is my code and I have trouble with email notification and delay on my apps when showing time. please help me

@Jose12 please edit your post using the pencil icon at the bottom and add triple backticks at the beginning and end of your code so that it displays correctly.
Triple backticks look like this:

please help me

Before you do anything, you need to sort-out your void loop.

Pete.

I can tell that you haven’t clicked the “Keep your void loop() clean” link yet, which is probably why you aren’t making any progress.

Click the link, translate the article into your own language, study what it says about calling functions with timers, not putting anything in your void loop other than the two essential lines of code, and then you might get somewhere.

Pete.
