If after the line t = input_on replace these lines
if str < 1 then scr = 1 end
if scr > 4 then scr = 4 end
with this, then you can move from the first sensor to the fourth (by pressing left), and from the fourth to the first (by pressing right)!
if scr > 4 then scr = 1 end
if str < 1 then scr = 4 end

@Geralt of Rivia, thanks! I'm currently studying at a university so I don't have a whole lot of time to do much, but if I get a chance I'll hop on and play with it (probly when the new DLC drops), or maybe I'll even make a whole new one that's better and scalable to the new different sized monitors.

love the micro controller but i was wondering if you could make is so i could move it around on a screen, for example having mutable dials on one monitor.
