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. Detailed Article with code -

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.

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.
Sorry for the long gap between videos, getting a bunch of other backlogged things done during the short Canadian summer. And THANK YOU To all of my subscribers - with your support the channel has passed the 100,000 mark!
And after making you wait so long for a new video I promise to keep "in touch"!
