Assigning ID's to textboxes

Hello, complete beginner here, currently I'm working on a project for app-compatible arduino alarm clocks, and I want to set 2 different alarms. How can I make it so that the textbox inputs have ids assigned to them so that my code will be able to differentiate between the two alarms? Ex: Alarm 1 has id of 0, Alarm 2 has id of 1.

You might send a positive number for one of the alarms, and a negative number for the other alarm.

Alternatively, use a text JOIN to add a prefix to the message, like
where nnn is the timer value.

Either way, you would need more code in the Arduino to pick out the message parts.

Hi, could you clarify how to execute your idea? Code-wise in the MIT App Inventor, what would I have to do? Apologies for asking, I am a complete beginner to this

Is this how to execute the join idea you mentioned? Let's say if my text in textbox1 is 08:30, and my text in textbox2 is 09:00, would the app send 0:08:30 and 1:09:00 respectively? If not, what would it send?

Is there any other information I could provide? Is my code in the latest post alright?
