main.ino line 8-11 and 17-20 --> digital pins for mux 1 and 2
main.ino line 14 and 23 --> analog pin for mux 1 and 2
main.ino line 41-45 --> analog pin for voltage sensor 1-5
main.ino line 74-78 --> analog pin for current sensor 1-5

line 185 --> change min and max loop value for different output
line 127 and 129 --> increase delay if data corrupt
