Hi all and thanks in advance to everyone who can interest about my aim.
My tools: I have created an app with appinventor that, connecting to the wifi created by the access point of the Arduino controller, is able to work as a remote controller. Indeed with the app I can set the work condition of a servo. The Arduino controller uses the WiFi.h Library and save the output of some variables in the SD in this format: #,#,#,#,#..... with n=20 and with a baud rate of 57600.
My aim: I would like to avoid the Sd card and to send, directly and with no latency, the same output in somelike a cloud or a file.txt or a page or a google sheets...everything (not arduino iot cloud where I need to pay in order to have some upgrade).
My desire: I would like to store as so much possible using only the App and the controller
My question: Do you have some direct examples about this request? Some specific documentation?
Thank You again.
