An arduino based pager with Nokia 5110 display, receiving (possibly also sending) data via DRF1278DM
Used an Olimexino Nano, as it
- operates at 3.3v, so no levelshifter is needed for the display,
- it has an SD-Card slot "on board".
- is based on a Leonardo which means it has a 2nd serial connection so software serial is not needed.
Button one is used to switch backlight on and off, and reset/delete all messages after a long press (>1s)
Button two is used to see new Messages and iterate through new ones
