let me explain,

i have a circuit network that has several signals on it

for example

copper = 100
iron = 10
coal = 5
stone = 5
etc

i have a chest where i can put one kind of item in (any amount, never mixed) it has to be a chest not a constant combinator or anything else.
if that item is for example any amount of coal the combinator should show the coal signal 5, if i insert any amount of iron in the chest the combinator should output the iron signal 10. etc etc

i have very limited experience with combinators so any help is appreciated.
Thank you for your time.

Search for "signal filter" or similar terms. I.e. this thread.

1. Pick one item and reduce the count to 1.
2. Change the count to 1 billion.
3. Add 1 billion to the matching signal in the dictionary.
4. Remove every signal less than 1 billion.
5. Subtract 1 billion from the matching signal.
