Ok, think I have figured this out, I used a button to set a variable to 60 the created a loop that subtracts .001666(=min using the 100ms logic timer) from the variable each time around. And use compare to turn on the output any time it’s above 0. Once the timer gets below zero it goes into negative numbers and keeps going. I don’t think there’s any issue with this but is there a way to stop the counter from continuing below zero? Will it ever run out of digits and start counting down from some large positive number if it just keeps counting down?
