What is ESP32 for Beginners?
ESP32 for Beginners introduces students to one of the most powerful and popular microcontroller platforms in the world of IoT and embedded systems. The ESP32 combines a dual-core processor, built-in WiFi, and Bluetooth all on a single chip — making it the go-to board for smart devices, wireless sensors, and connected projects. This course starts from absolute zero and builds up to real wireless IoT projects.
What You Will Learn:
- Understand the ESP32 hardware — dual core, WiFi, Bluetooth, pinout
- Set up the Arduino IDE and ESP32 board package
- Work with GPIO — digital input/output, analog reading, PWM
- Connect to WiFi networks and handle HTTP requests
- Build a simple web server hosted on the ESP32
- Use Bluetooth Classic and BLE for wireless communication
- Read data from sensors and publish to the cloud
- Use deep sleep and power-saving modes
- Build complete beginner IoT projects from scratch
