Arduino - Analog LED Thermometer

I originally thought this project might be too basic to share on Instructables, but I have since realized there is room for learning at every skill level. I hope you enjoy it. After reading numerous books and experimenting with many tutorials, I decided it was time to apply what I had learned and create my first “from scratch” Arduino project. I wanted to keep it simple but also provide the opportunity to try out some of the new coding techniques I had learned. I came up with the idea of a large-display thermometer that uses an array of colored LEDs to represent the traditional column of liquid. In theory, a completed project of this type could be housed in an enclosure and hung on the wall, where it would be easily readable from a distance.”
