A little while ago I asked a question on Discord and got some really nice help from someone there. I had been trying to build a data control loop that was a bit more sophisticated than a simple "bang-bang" logic loop. I wanted logic that would enable something when the number of my stored items fell below X, then disable that entity (a line of Assemblers) when the number of stored items went above Y. Bob_says_hello responded with a nice clever solution and I've been implementing it all over my factory. I decided to make a quick video to show how it works.
