I bought a serial enabled 16x2 LCD from amazon so that I could display the current temperature without having to go to my phone or computer. I guess that would be the reason but really it was just to see if I could. It turns out that it was very easy to get this working.
Note. I used a 09393 serial enabled 16x2 LCD. Some serial LCD don't work with the Arduino board so just make sure to do some research before buying one! I think you need one that has a TTL serial input. The link to it on Amazon is here.
There are quite a few examples and tutorials out there on the web and some did not work for me. Some required adding libraries and they did not work well for me. The simple built in Arduino code worked well and so I was happy using it. Here is the tutorial I followed. I 'll post up my updated sketch with a picture later.
