Aircraft Electrical System Simulation with LEDs

Our project is about simulating the elec system of an aircraft with the use of LEDs. The trick is that when you turn off the electrical line on the left side, the right electrical line will automatically power the side where the power is down or vice versa. So it shows the backup happening in the aircraft.

I’m not that good in arduino, but I’m thinking of using if and then statements. Will it be possible? There are about 15 events in total corresponding to each failure in the system.

Or what other approaches are possible for this project.

The picture shows the system to be simulated.
