I am still a very new to Arduino. But so far, I love it. Until now, I have successfully built the idea I had in mind, based on an Arduino Uno R3. It is just a counter based on an ultrasonic sensor which sends the "count" in realtime to an app I have developed via a Bluetooth component (HC-05).
Now, I would like to know if it is possible to store the count number on the Arduino itself, and only send the total when I request a synchronisation in the app. For example, the sensor counts 100 movements in a week and at the end of the week, I sync the arduino to my app. I would like the 100 result to be displayed into my app when I sync and reset the count to 0 on the arduino when it is done.
First of all, is it possible to store a value in the Arduino memory for some days? Would it be possible to do something even more ambitious and for example, store the count number for each days? And in my app, I would know how many counts have been calculated for a particular day?
Thanks for your help!
