Sending-Sms-Using-Twilio-Esp32

Course Description

This hands-on course teaches learners how to send SMS messages using the Twilio API with the ESP32 microcontroller. Aimed at beginners and intermediate IoT enthusiasts, it combines the fundamentals of networking, REST APIs, and embedded systems. By the end of the course, learners will be able to integrate Twilio’s cloud-based communication service into their ESP32 projects, enabling automated SMS alerts triggered by sensors or conditions.

The course includes practical labs, code walkthroughs, and real-world use cases such as home automation alerts, weather notifications, and security systems.

Certification

Upon successful completion of the course, learners will receive a Certificate of Completion indicating:

• Mastery of integrating Twilio with ESP32

• Proficiency in IoT communications using REST APIs

• Successful deployment of a real-time SMS alert system using ESP32

This certificate can be added to LinkedIn profiles and resumes to showcase technical IoT and cloud integration skills.

Learning Outcomes

By the end of this course, learners will be able to:

1. Understand the ESP32 Architecture: Grasp the basic features and capabilities of the ESP32 board relevant to IoT communication.

2. Set Up the Development Environment: Install and configure the Arduino IDE or PlatformIO for ESP32 programming.

3. Connect ESP32 to Wi-Fi: Programmatically connect the ESP32 to the internet to enable cloud communication.

4. Learn Twilio Basics: Understand how Twilio’s messaging API works and how to obtain API credentials (SID, Auth Token, etc.).

5. Make HTTPS Requests: Use the ESP32 to send HTTPS POST requests to Twilio’s API endpoint.

6. Send SMS Messages: Successfully send SMS messages from the ESP32 based on predefined triggers (e.g., button press, sensor value).

7. Secure API Communication: Implement basic security practices for handling API keys and HTTPS connections.

8. Deploy Real-Time Applications: Design simple IoT systems like temperature monitoring or intrusion alerts that send SMS notifications in real-time.
