I want to send an email when my Magnetic switch is HIGH. Magnetic Switch is connected to ESP32. So in which part of the code I should add this?
<
int Led = 4;
int magnetic = 5;
int val;
val=digitalRead(magnetic);
if (val==HIGH)
{
digitalWrite(Led, HIGH);
Serial.println("Motion detected");
delay(1000);
}
>
It might be a simple question but I am new in Arduino, and ESP32, so please help me.
I am following codes from this link https://randomnerdtutorials.com/esp32-send-email-smtp-server-arduino-ide/#comment-429759

Hi.
Move your variable definitions before the setup().
Move the other lines of code to the loop().
After detecting motion add the lines to send an email. I recommend creating a function that contains all the code to send the email.
I also recommend increasing the delay time a bit to prevent getting multiple emails.
Here’s an example (don’t forget to modify with your own details: sender email, recipient email and network credentials):

I hope this helps.

Hi.
The error says that password or email is not correct.
What email provider are you using? It may have different SMTP server settings. Did you check that?

Hi again.
If you’re using gmail, you don’t need to change the SMTP server settings on our example.
The error you’re getting says that the password is not valid. The password is for the email sender account, not for the receiver email account.
Without further information I can’t understand what might be wrong :/

Sara
