Is "Because" good enough?
I do a lot with them and find it an easier way for me
to control things via software rather than directly with electrical hardware. It's very easy to make software that controls hardware with the Arduino, and software is easy to tweak to make changes and adjustments - much easier than an all-electrical approach.
For example one idea is to have the actuator not start off with a fast movement (full on), but ramp up the speed to avoid stressing out the mechanism. Same when closing so it's not essentially slamming the door. I like the idea of tweaking a variable in my code to adjust things rather than modifying an electrical circuit.
Another idea is to create a new status board. I removed the old bus status board and also all the circuits, but still would like to have the various indicators about whether the doors are ajar and so forth. Again, easy to do with a little Arduino, existing door switches, and some LEDs.
The other thing is to use the Arduino for controlling interior 12v lighting and/or exterior "fun" lighting. If the bus is going to Burning Man again, let's just say it needs party lights
