Today we’ll learn how touchscreen displays work, both Resistive and Capacitive. We will also create a simple touchscreen interface using an inexpensive Arduino shield.

Today we are back in the workshop, working with an inexpensive Arduino LCD Touchscreen Display Shield.
We’ll begin by looking at how touchscreens work, both the Resistive and Capacitive variety. Then we’ll check out a great resource to download all of the spec sheets, libraries, and sample code for dozens of popular LCD displays.
After we get some sample code for pour resistive touchscreen display we will run through it and put our display to the test.
Finally, we’ll design a simple touchscreen interface to control three LEDs. You can use it as the basis for a more complex design.
Here is a breakdown of today's video:
00:00 - Introduction
03:13 - How touchscreens work
06:57 - Look at touchscreen shield
11:09- Obtaining touchscreen software
14:14 - Installing libraries and demos
16:24 - Touchscreen demos
23:13 - Arduino hookup

This isn’t the last time we’ll be looking at touchscreens, I have a capacitive touchscreen that I'll be showing you very soon.
So let's keep in touch!
