Hello, I need some guidance.
I've been using arduino quite some time now, but never actually wrote a sketch. For a project I am using a sketch with can be programmed by a lcd shield. Is it possible to have an android app taking over the function of the lcd shield via Bluetooth, so menu's can get displayed on Android device? Can I just replace lcd.print? Is there a tutorial that covers this matter? Basically I want to remote control the arduino because It will be placed in a 'hard to get to' place and I really want to use the sketch I'm using right now.
