 In addition to the functionalities explained before, both Opta™ are connected to Arduino IoT Cloud via Wi-Fi. Through Arduino IoT Cloud, both tanks can be monitored and controlled online.

 We will highlight the important details of the sketch that makes up part of the Opta™ in charge of the Small Tank. Notice that some of the functions in the code were generated by Arduino IoT Cloud during the dashboard configuration. We will begin with the required libraries. 
 
-These following headers are required to enable the RS-485 interface, connection with the Arduino IoT Cloud, and the scheduler. The scheduler is used to handle the data exchange over RS-485 interface, while keeping the `loop()` to manage local parameters of the Small Tank.

-It is possible to notice whenever an Opta™ exchanges information with an another Opta™ over RS-485 interface, subsequent structure of code can be observed. In this sketch, it uses a single character to represent a flag state of a certain module to be recognized by receiving device to use this flag as a conditional for designed operations.

-Thus, when such characters are received and decoded, it can be used to determine whether to activate certain module or if a certain module attached to sender has been activated. In this example, if we receive `V` from the Big Tank Opta™, the Small Tank's valve must be turned off. If it receives the character `1` or `2`, the Small Tank will have the information regarding Big Tank's minimum level. Following simple parser does this task inside the Small Tank's Opta™.

The `BT_System_Off()` is triggered if minimum level flag is turned off, in which will halt the Pump and send the valve off command for Small Tank's Opta™. This is the emergency stop for the system. The `BT_Pump_CTRL()` will send the valve off command whenever Big Tank's maximum level is reached and activate the pump to avoid reservoir overfill.
