How to send an email with Arduino by pressing a button?

• Step 1: Before you begin, make sure you have all the necessary materials: an Arduino, a button, some cables, and a stable Internet connection.
• Step 2: Connect the button to the Arduino using the cables. Be sure to follow the manufacturer's instructions for a correct connection.
• Step 3: Download and install the Arduino software on your computer if you don't already have it. You can find it on the official Arduino site.
• Step 4: Open the Arduino software and create a new project. This is where you will write the code necessary to send the email.
• Step 5: Write the code needed to connect the button to the Arduino and send the email. You can use libraries like “WiFi” or “ESP8266” to make the process easier.
• Step 6: Be sure to include your email address and mail server details in the code. This will allow the Arduino to connect and send mail correctly.
• Step 7: Check the code for errors and upload it to your Arduino board.
• Step 8: Connect your Arduino to power and press the button. If everything is set up correctly, the Arduino should connect to the Internet and send the email.
• Step 9: Check your email inbox to confirm that the message was sent successfully. If all goes well, you will have sent an email with Arduino with the push of a button!
