Arduino Email Sending

Hello, I have a school project where i have created a simple security system using PIR sensor and a buzzer. I have created this project like this one https://makezine.com/projects/pir-sensor-arduino-alarm/ In my project i want to send an email or a notification to a phone without buying new modules. If required i can only purchase the ESP8266 wifi arduino module. I want to send an email when the PIR sensor detectes motion. In my project i dont have any modules i only have arudino uno, buzzer …

It seems that the port settings may need to be changed in your script file.
