I'm planning to build a simple alarm clock (show time, at least 2 alarms, play mp3 sound).
My first hardware problem is the display. I'd like to use a 3,5" lcd graphics display. Doesn't have to be a touchscreen.
But: most of them connect to the gpio. I need to add some buttons for the settings. Is there a small, affordable display that connects to the RasPi display port?
And: it should be possible to set the display to be realy dark but still readable during the night and day. Even most commercial alarm clocks are way to bright for a bedroom.
