Arduino Ignition Controller

Projects General Guidance
1

I'm looking for a little guidance on how to complete this project. I have a good bit of knowledge in C# coding and basic knowledge of electronics but no experience working with Arduino. Any help you guys could offer will be

I want to use different timed lengths of an analogue input to open three relays (one after the other) and then close them when the input is powered once more.
e.g. one-second hold opens relay 1, two more seconds held (total three-second hold) opens relay 2, two more seconds held (total five-second hold) opens relay 3 and closes it when the input is off, then finally when the input is returned once more all the relays close and the system powers down.

Like I mentioned above I have a pretty good handle on C# programming but I could use some help with the inputs, outputs and the timing of the input.

I have an Arduino Nano (Not sure which one, it was a gift) and a 4 channel relay board.

Any help you can provide will be much appreciated!

I can think of a few ways to do this with just about any Arduino board.
First, draw a diagram of how you visualize the project.
Second draw a timing diagram of the relay operation.
What is the trigger?
Why do you want to use the analog input?

Update! I received some unexpected help! Thank you for your quick replay all the same SteveMann but I've got the code I need now.
