[arduino code examples for F16]-03 Read analog input ports value

[admin]

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 5
* - A2: GPIO 7
* - A3: GPIO 6
* - A4: GPIO 4
