// Libraries ----------------------------------------------------------------
/** Arduino.h includes many items for the Arduino-environement.
  * No need for guarding against multiple library inclusions in the Arduino 
  * environement.
  *
  * Arduino capabilities & items listed by ChatGPT:
  * 
  * What Arduino.h Provides (Core Arduino API):
  *
  * === Types & Macros ===
  * - boolean, byte, word
  * - HIGH, LOW
  * - INPUT, OUTPUT, INPUT_PULLUP
  * - PI, HALF_PI, TWO_PI, DEG_TO_RAD, RAD_TO_DEG
  *
  * === Timing Functions ===
  * - millis(), micros()
  * - delay(), delayMicroseconds()
  * - yield()
  *
  * === Pin Control ===
  * - pinMode(), digitalWrite(), digitalRead()
  * - analogWrite(), analogRead(), analogReference()
  *
  * === Bit Manipulation ===
  * - bitRead(), bitWrite(), bitSet(), bitClear()
  * - lowByte(), highByte()
  *
  * === Serial & Stream I/O ===
  * - Serial, Serial1, etc.
  * - print(), println(), read(), available(), etc.
  *
  * === Math Utilities ===
  * - abs(), constrain(), map(), min(), max()
  * - round(), sq(), sqrt()
  *
  * === String Support ===
  * - String class and methods (length(), substring(), indexOf(), etc.)
  *
  * === Random Numbers ===
  * - random(), randomSeed()
  *
  * === Interrupts ===
  * - attachInterrupt(), detachInterrupt()
  *
  * === Type Aliases ===
  * - uint8_t, int16_t, uint32_t, etc. (from <stdint.h>)
  *
  * === Program Memory (AVR) ===
  * - PROGMEM, F(), pgm_read_byte(), etc.
  *
  * === Board-Specific Additions ===
  * - ESP, SAMD, etc. may add features like ESP.getFreeHeap(), etc.
