Thank you for pointing that out. I can see why they would have that warning, and I've designed the system as a "fail safe" system. Should a bag blow or the control circuit fail, the bump stops will prevent the car from bottoming out & I can drive it until I can resolve the issue....
The damping idea is new to me & sounds interesting. Thanx for the links. I briefly looked at it just now, but seeing as I'm just feeling my way through this, I'm more than happy to skip the damping method for the time being and just focus on the rough on/off control.
It won't be as elegant as the damping method, but it will still be a closed loop feedback system, won't it? It will turn the solenoid on/off while still monitoring the input....which is exactly what I'm after.
Focusing on case 3, how would I go about doing this?
Also, in regard to the potential divider, do you mean use 2 resistors to drop the vehicle's 14v down to 5v and then feed this into the analog input and have the arduino monitor it until it drops below a pre-set threshold?
