You can not work with this special funtions via Mobiflight BUT you can use this Pins !
All Pins are worked like digital 1/0 Pins in Mobiflight ( Pin 14-21, too)

Only exception ... Pin 20 and Pin 21 ( SDA SCL ) is used for the LCD IC2 Communication.....
If you set a LCD Display on THIS Arduino then it MUST set to 20/21 .... In That Case you can NOT set a switch, LED or other device on that both pins.
If you NOT use a LCD on that Arduino, then Pins 20/21 can used for everything as i said above !
