Installing a UI to change simple things in the code

Projects General Guidance

Hi all

I have my arduino uno working as a monitoring device which sends me readings in a SMS

Does anyone know if it's possible to have some kind of user interface on the actual device where I would be able to change the phone number that it sends to??

Im aiming to just make things more simple and eliminate the need to plug a laptop into it to change stuff.

Any pointers would be much appreciated! Thanks

Should be very simple, any switch connected to an input can be used to select one number or an other.
If you want to make the code generic then store the two numbers in EEPROM.

An old fashioned rotary telephone dial would be cool, and it's serial!

If your device is capable of receiving sms just set it up via a configuration sms.

"SMS TO 555-123-4444"
