Hey Friends!
I'm making a device to send a text message when a room gets too hot or cold. Rather than having to go in and edit my arduino code and recompile every time I want to change my upper and lower temperature limit (I will be changing these numbers frequently), I would like some sort of 'knobs' I can turn- maybe have a digital screen or something to show what the current high / low temp limit is- that can update the temperature limits in a live sort of way.
Any thoughts / guidance?
