New to Arduino and coding...

I mainly need some help with the coding the wiring I can do it

So simply put

I want to make a control box to ignite firework

With about 7 input and 7 output

I need to make that every time a signal is sent (button pressed ) and output need to turn on for 10 seconds minimum

one last thing I will have LED around my button and I want them to stay on after the button is pressed

the output will be relays where I will have a larger power source to ignite electric fuses
