Have a buddy that’s going to give me one to try it on just have to get it from him

I could have a millisecond of hang over. It’s not a critical situation. It realistically can be broken down to a 2 in 3 out situation. Just 2 times. If one is pushed 2 outputs activate. If two inputs activate one output basically falls off and the other stays activated. Basically if both inputs are ...

It’s human inputs. I have 2 sets of 4 in 4 out. At most I would have 2 in and 3 out being toggled.

So what do I need to purchase to do this

It is realistically 2 groups. 4in 4 out per group. They would only see at maximum 2 inputs at one time per group but at a maximum of 3 outputs per 2inputs

I’m not sure which language is best or easiest to do what I’m wanting.

So im trying to see if this is possible and someone suggested a Pi.. i have 8 inputs that need to control 8 outputs. but the kicker is that i need them to control multiple outputs dependent upon inputs activated. Example: INPUT 1-8 OUTPUT 1-8 INPUT 1 would activate OUTPUT 1&4 INPUT 2 would activate ...
