While the serial display is interesting, it has some limitations. It is difficult to display pictures or graphics, and it is somewhat slower than other interfaces available to you. So, let's add a display with a different communications interface. The following image shows a picture of a small, 1.8 inch LCD module with a micro SD card interface that can be connected to your Arduino:
This particular display is available from a company called SainSmart; it is available directly from the company or other online retailers such as Amazon.com. There are others that are very similar. Finding support for these displays can be difficult, as the interface is significantly more complex; so, check to make sure the libraries are also supplied with the display. To connect to this display, perform the following steps:
The first step is to connect the display to your Arduino. The following image shows a picture of the back of the display that will help you connect...
