| The idea from which I started this project would be that we always forget to water the flowers, and in agriculture or even in the flower garden (or even the few flower pots in everyone's apartment) monitoring the soil moisture is imperative. If we want to have good crops or flowers that are healthy and grow beautifully. | The idea from which I started this project would be that we always forget to water the flowers, and in agriculture or even in the flower garden (or even the few flower pots in everyone's apartment) monitoring the soil moisture is imperative.

| + | **CONFIG PHASE**\\ | ||
| + | In this part of the code I have defined macros and declared global configuration variables specific to the operation of peripherals, connections to servers and APIs that will allow us to make various setup function calls in the next step.\\ | ||
| + | |||
| + | **setup()**\\ | ||
| + | At this step all the initializations of peripherals, services, etc. that we need are done:\\ | ||
| + | |||
| + | - the serial is initialized with the boudrate of 115200 | ||
| + | - the LCD screen initializes | ||
| + | - trying to connect to the network via WiFi by calling the try_connect_WiFi() function | ||
| + | - initialize connection to NTP server and test requesting current date via print_localtime_test() | ||
| + | - SMTP is initialized with smtp.debug(1) to print the debug mode of the service on the serial and with smtp.callback(smtpCallback) the callback function is set to obtain information about the status of the email being sent | ||
| + | - the SMTP session is initialized with the call of the set_session_config(ESP_Mail_Session*) function and the header of the message to be transmitted, by the call of the set_message_header(SMTP_Message*) function | ||
| + | |||
| + | **loop()**\\ | ||
| + | This is the main loop. Once you reach this stage, the code described in the loop() function will run indefinitely(endless). Basically here is a description of the functionality of the entire system. The following main operations are performed here: | ||
| + | - the call of the compute_moisture_percentage() function is made and the soil moisture sensor is read and the obtained value will be transformed into percentages. | ||
| + | - the information is displayed on the screen. | ||
| + | - by calling the MQTT_connect () function we connect to the feed in the dashboard on io.adafruite.com | ||
| + | - data is published calling SoilMonitoring.publish(moisturePercentage) | ||
| + | - by calling the get_time_hour() function I request the NTP server for the current hour and minute and then I check if they are the ones I specified. if this condition accomplished i will call send_message(String) | ||
