I wanted to do a simple project for my newly acquired 16×2 LCD display, and thought I should do an indoor thermometer. I searched around a bit online but couldn’t find exactly what i wanted to do, most projects where indoor/outdoor. I did however find this great tutorial here on hooking up the 16×2 LCD with 2 pots.
I added my LM335z temperature sensor, hooked up my arduino, made a little sketch to output the temp to the serial monitor. It was 3 degrees off and that could have easily been fixed with a another pot however i only have 2 and used them for the LCD display. Here is a diagram i made with fritzing.
And here is a very poor photo of the finished project.
