Pinout Interfacing & Testing Guide:
Check the silkscreen pin labels (VCC, GND, SDA/SCL or I/O) and confirm whether your microcontroller uses 3.3V or 5V logic.
Wire the power, ground, and signal pins to your Arduino, ESP32, or Raspberry Pi using breadboard jumper wires.
Upload a standard test sketch via Arduino IDE or MicroPython and verify live readings on the Serial Monitor.
