I had a few scrolling Led displays from a project at work. I took one home to work on some ideas for what to show on it. The only problem was it was a serial display and I didn't like being tethered to it.
I used a Linkit one to make it bluetooth. So far the best use is to show game scores in Unreal Tournament 2004. Probably not a good use for work though.
I'd like to use the Linkit's SMS capability to override the current message with any SMS message received. My thought is that I would enroll the SMS number in my schools Campus alert system. That way if there's a problem I'll know about it.
That would be a great off campus alert screen. I'd love to see those weather closing messages before I get out of bed.
If I do the same with the Wifi connectivity I may be able to use it on campus too.
I made a simple serial interface board for the Linkit One. I used a Max232CPE chip and 5 small 1uF capacitors just like the standard test setup in the data sheet.
The code is pretty simple. I have to figure out if the Linkit can do UDP calls then I wont need my computer at all. Right now my Macbook runs UT Query and sends the data up to the screen.
The SMS should be easy but My Sim isn't registered yet. I just got it and have to see if its recognized by the Linkit.
