Hello, I am Some what New to Coding and i am taking on a somewhat new project for me. I am Building a power supply and i am making a Arduino Fan controller for it. I would like For the 16x2 display To show something like this (Look at The Image Hard to explain)
But I Just don't know how to do the code, so can someone help me. The original code was found on this website http://www.electroschematics.com/9540/arduino-fan-speed-controlled-temperature/ But i modified everything for my needs current the LCD Please Help Here is my current code
[code]
