help!!! 12 buttons in the bus,station number by 7-segment display, for proteus desig

[songemi53]

can u help me. If the stop button is pushed, metrobus will stop at the next station. There are four doors and each door is related with only three buttons (so 12 buttons in the bus). When a button is pushed, the related door should be opened.
If there is no stop button caveat (warning), the bus passes the next station but it announces the station name (or just show the station number by 7-segment display)

There are additional two warning inputs; the first one is for alert situations, alarm button. If the alarm button is on, the bus should stop and open the doors. The second one is blocking input. Blocking input gives '1' to the circuit, in case the bus-road is blocked

I assume you want help to write the software.

The first step is to draw a flow chart.

So I suggest that you do this and post it so we can comment.

No-one is likely to do it for you. We are here to help, not to do other people's work for them.
