Arduino Touchscreen Display - Using a Resistive Touchscreen

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
24:18 - Arduino sketch
34:48 - Our Interface in action

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!

Anyone noticed that he uses multiple cameras and often change his perspective from one to another camera like in professional TV shows. This Channel is 100% quality!

Hi DroneBot, i like your clear pronunciation! It's very often hard to understand some english speaking bloggers because my native language is german. But following you is very easy.
Even your recitation is very interesting and I can participate a lot.

Excellent, a great learning resource! I learn loads every time I come to the Workshop!

[insoft_uk]

Demos I find are great to test the product that it works, the first one cycles through the R G B which I think is the most useful checking for dead stuck or lazy pixels

Just discovered your channel. Wow! What great content for people interested in this sort of stuff. Disappointed I hadn't stumbled upon it sooner. Subscribing and planning to watch all your old Arduino vids!

Looking to build a DIY star tracker and this is just the thing I was looking for, to add a touchscreen for real-time speed adjustment.

Yet another excellent video. Your attention to detail makes you the King of How To. It's comforting to see you back with your mind-blowing videos. Thank you so much for what you do.

[peterhuesmann]

Fantastic, just what I was looking for!

[redst]

Your video is inspiring. I've never thought a touchscreen can be used with an Arduino.

[hubertmargreiter]

Excellent presentation, thanks for uploading.

Thanks for this video tutorial and learning. Because of you, I purchased the same touchscreen and tested it today! Wow, this is fun! Can you imagine that in the early 90, I prototyped a wire-wrapped MC68HC11 to create something like an Arduino and I wanted to interface to an LCD? At that time, LCD screens were extremely pricy!

Here I'm, some 25-30-year latter, getting back in the µcontroller world and with the internet, information and tutorials are so easy to find. Luckily, I found your channel on youtube. I found your videos so informative that I've joined your newsletter as of today (2020-01-09).

Again, thanks for the quality of your video.

So detailed explanation.Great tutorial!Thanks for your sharing.

[lorinfortuna]

A+ content. covers most of the "Why is that?" questions :)

[MiCoopRS]

WOW, all your videos including the very OLD ones, 2019...even...I just or have already subscribed and continue to spend hours watching and then applying the things I have followed along on....sometimes, my project does not work at first, however, seems I am a good trouble shooter. I have purchased 5 tiny Nano brds, to make the projects smaller and I'd rather install the working Nano, v2 a Arduino UNO R3, but the first project I tried, well, the computer could not detect the usb...Oh it could be a BAD cable, yet there was power....OH WELL, this is the FUN or learning...Starting from NANO to UNO... I'll keep researching... I wanted to REACH OUT and say, YOUR stuff is amazing... keep up the Great work... I had a few days off work and have just begun my journey back into Electronics.... not yet retired but you got to keep the BRAIN Merry Christmas and Looking forward to a better, we all 2021

Hello, well impressed with your presentations videos in the DroneBot workshop, Your teaching style is without waffle, to the point, informative and well structured. I am now revisiting after many years the Arduino and Raspberry prototyping tools. However, what I also found interesting from your videos, was the design layout of your workshop. As I am now retired I want to revisit a lot of the projects that I have shelved over the years.
First things first I want to build a compact but well facilitated workshop that will meet all my requirements from electronics, metal work and woodworking. Would it be possible for you to make a short video outlining how you designed and facilitated your workshop. I thing this could be of great interest to others like me. thank you once again for your commitment to helping others.

[raysanders]

I should have watch your video three days ago, thanks. Excellent video. Best ever.

[steveweiser]

Very Nicely explained, I am an electronic enthusiast and a new subscriber to your channel.

[thomasmcann]

Your work on YouTube should be shared more, every kid needs to see your work, I think it should be compulsory, the tech is there to enslave machines and get them to work for us

[daveharkin]

Just like to say thank you for your videos, I really appreciate the time and effort you put into them, please keep them coming

[osamarabee]

sir you are a great teacher i really love the way you explain stuff i hope you still in a good shap and health and happy for ever i love you man
