user87358: my final year project is to do an Arduino watch that has heart rate and body temperature sensors and also a location tracking module. I need to send all the watch data to my java app but I don't how do I need to send it to a database first and then use it? and how can i do that.
I'm using arduino uno and i want to send the data to a database on a server.
I'm using android studio and coding with java
please help :(

user7508: To send the data from the Arduino, you just need to do this:
Serial.println(the_data);

But then you have to manage some communication link between the Arduino
and whatever is going to collect the data. Typical choices are the USB
link or a Bluetooth module. Then, whatever you do with this data (send
to an Android phone, a Java app, a server, a database, whatever...) is
up to you, and is not an Arduino question.
