learned some more about analogRead. pretty much cut and dry. It seems to work but has incredibly slow response time. I understand it will need to make one complete pass through the code before it updates but i put in the print serial command and it's taking 2 trips through the code before it updates. it is put someplace wrong? The code is posted 2 times so i can show the bold where i've made changes.
