Filteration diode slide display program

​Simple program to connect 3 filtration units and 3 diode slides to single integrated circut I named it Oxygen/carbon/nitrogen - but obviously you can change them to match 3 filtration units your using. I used to use a ton use a wall of logic chips for each filtration unit - 1 slot reader per slot, math proccessers to add both slots together, then devide everything by 200 to get the percentage for the diode slide to display since it shows between 0. and 1. 0 This is my very first self written program - based on watching Greyduster filter warning video and Saddamo De Beers diode video I combined the knowledge and this is the result. im sure its probably longer then needs to be or otherwise - but it works.. took a bit of trial and error though. Enjoy / like / sub /etc yada yada
