About Lesson

A. Installing Required Libraries

  • Arduino IDE Setup:
    • Ensure the ESP32 board is installed in the Arduino IDE (as outlined in the previous lesson).
    • Open Arduino IDE and go to Sketch → Include Library → Manage Libraries.
    • Search for “Adafruit SSD1306” and “Adafruit GFX” libraries. Install them.

B. Checking and Installing Libraries

  • Ensure that the libraries are installed correctly.
  • Demonstrate how to check installed libraries in the Arduino IDE.
