Hello. I'm a software developer and wanted to get an arduino to mess around with apps communicating to external hardware. I found some great libraries for creating the modem and encoding the signal (arduino) and decoding the signal (iOS), but I havent found any great schematics for actually building something simple to actually send the signal.
My first project is to have a button send a signal to the iphone to toggle the background color or something - basically proof that I can get it to communicate properly first.
Any suggestions or guidance would be really helpful. Schematics or something would be really helpful.
If you have these great libraries you may want to share the links to them with us? What kind of Arduino are you planing to use? The Due has DACs onboard so you probably have another type in mind.
The project was made in 2012 so the code is a little dated (odd that so much changes in two years) and I had to rebuild the project to get it to execute. I plan on writing a cordova plugin to send data back and forth between javascript and the native code so I'll post that once I get it all put together.
