Add graphics, real-time information display, and a dynamic user interface to your microcontroller project with a touchscreen!  In this instructable, I'll show you how to use a touchscreen to:
  • Display true-color images
  • Create a dynamic user interface
  • Show data with gauges and dials
  • Use touchscreen input in your project
Continue to the next step and I'll show you a few demonstration projects to get you thinking, then I'll show you the parts you'll need and how to include a touchscreen with your project.
