Yes, i had to change delay 1000 or higher to avoid flickering on LCD because i like it detects cable in real time when plug/unplug without using switch.
I was thinking if is possible i can run multiple codes for 12 wires, 8 wires...
I did some research in the forum about call function(1) (2). Very interesting!
Right now i have 2 types of cable to test (8 & 12 cond) and i am wasting 2x Arduino Mega for each... i am still learning
