Lesson 2: Interfacing Sensors with ESP32 & Wi-Fi Provisioning

Wire up I2C, SPI, and ADC sensor peripherals to the ESP32 dual-core microcontroller and implement Wi-Fi reconnection routines.

I2C two-wire bus: SDA (Serial Data) and SCL (Serial Clock) with pull-up resistors
ADC attenuation settings for 0-3.3V voltage readings
Non-blocking timers using millis() instead of delay()
