Need Help With My Project Mega 256 Notification to Gmail

Hi. I use Blynk and the example of sending an email if I connect Gnd to pin 2. When the email is sent the application disconnects. What should I do so that it does not disconnect and I can send several emails?. My hardware is: Arduino Mega 256 y Shield Ethernet W5100

What do you see in your serial monitor?

Pete.

The Gmail notification is successful, but then the app Blynk says: Offline

Can you turn on timestamp in the serial monitor and repeat this please?

Pete.

If I close the monitor and reopen it, the system returns to normal …

I think the issue is that you are getting is switch bounce from your switch on GPIO2
This is causing the limit of one email per 5 seconds to be exceeded.

Maybe add a debounce routine to the interrupt handler?

Pete.

Maybe add a debounce routine to the interrupt handler?: Can you help me how I do it and in which part of the code is it inserted?

This isn’t really a Blynk issue and there are lots of examples of interrupt debounce routines on the internet. Here is one example…
https://forum.arduino.cc/index.php?topic=45000.0

If you are using this example…

https://examples.blynk.cc/?board=Arduino%20Mega%202560&shield=Ethernet%20Shield%20W5100&example=Widgets%2FEmail

then it would go in the Interrupt Service Routine, which is called void emailOnButtonPress()

Pete.

Thank you for your collaboration :+1:
