What the program should do:

A. Switch on procedure
    1. Bridge switch on default position at 0°
    2. Sensor on bridge to test for locomotive on the bridge
        a. If there is locomotive on the bridge
            i.   Display - "Bridge is occupied"
            ii.  Switch on Amber LED's on bridge
            iii. Move the bridge to 0°
        
        b. If bridge empty (and not at 0°)
            i.   Switch on Amber LED's on bridge
            ii.  Display - "Bridge is moving to 0°"
            iii. Move the bridge to 0°

        c. If locomotive is moved onto the bridge
            i. Switch on flashing Amber LED's on bridge
            ii. Display - Bridge is occupied
        
        D. If there is a locomotive inside the loco and the loco is selected
            i. Switch on flashing Amber LED's in front of the sched
            ii. Display - Loco sched is occupied

        E. If there is a locomotive inside the loco
            i. Switch on Amber LED's in front of the sched

B. Operational procedure
    1. Select a number on the keypad
        a. Key selections 
            if key = 0 to move the bridge to 0°
            if key = 1 to move the bridge to 115°
            if key = 2 to move the bridge to 85°
            if key = 3 to move the bridge to 55°
            if key = 4 to move the bridge to 25°
            if key = 5 to move the bridge to 345°
            if key = 6 to move the bridge to 315°
            if key = 7 to move the bridge to 285°
            if key = 8 to move the bridge to 255°
            if key = 9 to move the bridge to 180°
            if key = A Invalid key
            if key = B Invalid key
            if key = C Confirmation key
            if key = D Invalid key
            if key = * Invalid key
            if key = # Invalid key

General:
The bridge can either be moved directly to 180° from any position or to 0° from any position. BUT - the front end of the bridge have to stay at the closest point to the scheds, except when it is turned 180°
