I'm looking to have a countdown timer based on time. I already have a tag for the current time that is always displayed. What I'm looking to do is for other LEDs to countdown for breaks and lunch for production and stop the "takt" time, then start the "takt" time after the countdown is completed.
Never heard of takt time, but can you just calc the seconds between the break times / lunch time and the time "now" to get your seconds remaining? Or maybe I'm misunderstanding something..
