[arduino code examples for A32 Pro]-03 Read analog input ports value

Code:
/*

 * Made by KinCony IoT: https://www.kincony.com

 *

 * Description:

 * This Arduino program reads analog values from four analog input pins (A1, A2, A3, A4)

 * and prints the values to the Serial Monitor. The analog inputs are defined with specific

 * GPIO pins and the program reads the voltage levels from these pins every 2 seconds.

 *

 * Pin Definitions:

 * - A1: GPIO 7

 * - A2: GPIO 6

 * - A3: GPIO 5

 * - A4: GPIO 4
