Documented Code

No code has been provided for the microcontroller. The documentation of the code would typically include setup and loop functions for Arduino-based microcontrollers, initialization of sensor libraries, and logic for reading sensor data and performing any necessary data processing or communication tasks. Since no code is available, this section cannot be completed. If code becomes available, it should be documented here with explanations of its functionality and purpose within the circuit.
