Help with Arduino

[Hitaya 1]

Hi people, 

I have some questions for a small program i'm started to make in Arduino.

The program's overall picture is that when using the serial monitoring, u will be able to write "New User" or "List". If u type "New User" u will be able to write different user information down such as name and age, after where you can store the user. if u on the other hand type "List" u will be able to see the entire list of users there are stored. 

I'm not the best to Arduino, but I know the basic as string, arrays, loops and structs. 

Can anyone help me ?

The serial works pretty much like an TERMINAL, but the functions are a little bit different

 

Since serial is a port used for communication, its latency is a bit high, and it probably doesn't raise an interrupt on the microcontroller. Therefore, the arduino can't listen to it constantly, like in a computer. So, you can't simply scanf() for a variable, but you can print(), since print is a output stream. Idk if I made myself clear, but whenever you are trying to read values from the serial, you will have to use other functions, rather than scanf(), from C.

 

Take a look: 

Please login or register to see this link.

You have some functions, like read(), parseInt(), etc. Take a look! There are all the functions and working examples there. The documentation is always a great way to start.

 

Lemme know if you need further help
