-In version 1.4 you can use clock verticaly and show some short messages (you can use two inputs). If you connect input 10 and/or 11 to GND you can show one of them. You can upgrade text of message only in code, see row around 420 (look for '//show some message or time'). More information in code.
+In v1.5 it's possible to invert display and control clock by a IR remote control. You have to change IR Remote control codes in sketch to your codes. You can use...
