+/**
+ * Re-maps a number from one range to another.
+ *
+ * This function behaves similarly to the Arduino `map` function. It takes a number defined 
+ * within a certain range (inclusive) and maps it to a new number within a different range
+ * (also inclusive). Optionally, the function can allow the output to exceed the mapped range.
+ * The function is especially useful for adapting sensor values or other input data to a specific scale.
+ *
+ * @param {number} x - The number to re-map. Expected to be within the range of in_min to in_max (inclusive).
+ * @param {number} in_min - The lower bound of the current range of x (inclusive).
+ * @param {number} in_max - The upper bound of the current range of x (inclusive).
+ * @param {number} out_min - The lower bound of the target range (inclusive).
+ * @param {number} out_max - The upper bound of the target range (inclusive).
+ * @param {boolean} [allowExceed=false] - Optional. If true, allows the output to exceed the specified range.
+ * @return {number} The re-mapped number. Constrained within out_min and out_max if allowExceed is false.
+ *
+ * @example
+ * // Map a sensor value from a range of 0-1023 to a range of 0-100
+ * let sensorValue = 512;
+ * let mappedValue = map(sensorValue, 0, 1023, 0, 100);
+ * console.log(mappedValue); // Outputs: 50
+ *
+ * // Example where output exceeds the range
+ * mappedValue = map(sensorValue, 0, 1023, 0, 100, true);
+ * console.log(mappedValue); // Output may exceed 100 if sensorValue > 1023
+ */

+/**
+ * Clamps a number between two inclusive bounds.
+ *
+ * This function forces a number to be within a specified range. If the number is less than
+ * the lower bound, the lower bound is returned. If the number is greater than the upper bound,
+ * the upper bound is returned. Otherwise, the original number is returned. Both the lower and
+ * upper bounds are inclusive.
+ *
+ * @param {number} value - The number to clamp.
+ * @param {number} minVal - The lower bound of the clamping range (inclusive).
+ * @param {number} maxVal - The upper bound of the clamping range (inclusive).
+ * @return {number} The clamped value.
