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!

They were very random to me 😂 I rewind a bit to hear he uses it for different topics but I couldn't notice a schema

[@rudolfherwig7279]

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.

[@acestudioscouk-Ace-G0ACE]

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

[@forrestberg591]

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!

[@Mystic0Dreamer]

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.

[@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 exercised..... Merry Christmas and Looking forward to a better, we all hope..... 2021

[@redst292]

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

[@geoffthomas8528]

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.

[@lorinfortuna1547]

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

[@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

[@raysanders332]

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

[@daveharkin4731]

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

[@YFtouchscreen]

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

[@donaldwright2426]

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.

this is the best teaching channel

[@robbyprust]

Nice video , you always explain things in detail . I have that same display and the touch screen part stopped working . Good display except for that ,but your explanation of how the touch screen works has me exploring what might be wrong with it. They are so expensive though

[@EL34XYZ]

I messed up and bought a 3.5 LCD without touch from Ali Express. I ordered the correct one with touch. Looking forward to using a touch screen

[@wendygrant2735]

Well explained as always.👍👍👍

[@bobengelhardt856]

Very professional video - thank you for presenting it. At the end you mention that there will be another video on capacitive TS & other examples. I can't find that video - do you have a link?

[@Corbald]

The biggest drawback of resistive screens is that it's relatively easy to wear a groove into the surface, especially along UI elements like scroll bars.

[@jnkmal9519]

"...we're back in *TOUCH* today." I see what ya did there. Nice!

[@raagamparmar179]

Hmmm...... Interesting. The display can be used to make an interface for home automation system, as in the project made in the video.

[@michaelhawthorne8696]

Brilliant video !.....I have one of these displays but only have an UNO... I might invest in a Mega. I have a 7" touch screen from Kuman, I might dig that out too. That LCDwiki is a fantastic site. Thanks for uploading.

[@ALGH2101]

Now that's a nice set of tools! Whats your favorite brand, type ,and size cutters for cutting the ends off things like R, C , L's leads that are not needed and sticking out from soldered circuits?

Thank you for this video, it helps me a lot. But could you please explain how to add a MicroSD Card Adapter to the display, because I use a Arduino Mega 2560 and I need the pictures from the SD Card for my project.

[@cheerstolove5078]

Hie... I have a request. May you kindly do a series on QR or BarCode modules such as the RT830C or 870. I could not find any solid tutorials on those

[@THE16THPHANTOM]

can you use shift registers to increase the nano pins? would that make the libraries completely useless and require some rewriting to compensate? i have no time to go hardcore mode and write the software myself.

[@saydiy1528]

good job. can you show a round image in a round area instead of a rectangle area? thanks.

hello Peter, do u have the needs for the LCD Screens?

[@essamaframhanna]

Thanks for this Excellent video, I wonder to know how can I use the same 3.5" LCD and OV7670 Camera connect to Arduino UNO, to get Live picture.. Of course I'll use Breadboard instead connecting the LCD directly to Arduino, Neglecting touchscreen pins..

[@josephanthony9294]

Excellent video as ever. I have an identical board where all the demos work but will not accept any touch input. can anytone tell me which pins I can use to measure the touch resistance. I am beginning to wonder whether screen is faulty. Thanks

[@fireteamomega2343]

There's so many different screen shields usually if it doesn't work it's because you have the wrong library drivers ILI9486...81...84 ?. Does the touchscreen calibration example work ? If not find you must one that does. Be sure you have Ts touchpoint lines included TS_MIN MAX as well (set from your calibration) it sets up p object value and screen size parameters. Bool also needs to be set false true false usually it's assigned to ifpressed. Throw read resistive code everything serial monitor down into loop. Run it pull up serial monitor and write down the x y values where you are touching. Then finally check your if (t.x < && line numbers I often put in the opposite values then realize when it doesn't work that my numbers are backwards.

[@allouette401]

Very happy that you are back .

This is the only person in front of the camera ,on KZbin, that's more concerned with content accuracy and production quality. He should be on PBS or some other educationally driven outlet. In a perfect world, Bob Ross would still be painting Happy Trees followed by The Drone Bot W.S. to give us a well rounded Sunday morning lineup.

[@qzorn4440]

very, very nice video I am repairing a CNC 3-axis milling machine, Siemens Windows_NT Acramatic 2100 LCD display with a 5-wire 14" touchscreen. The touchscreen went bad, do you have any suggestions? I would like to just replace the stick-on touchscreen with the ribbon cable and connector with may be the glass window. thanks. :)

[@thanassissarakatsianou2290]

First of all, I thank you for your excellent and detailed videos you offer to the public! I was wondering (because I'm in the middle of a project) if it's possible to have an ethernet shield and a touch LCD screen (like the one you 're presenting in this video) connected together on an Arduino Mega?

[@mecatx]

Great video. I am trying this setup with a DHT22. How do i get power tot he DTH22 form the mega arduino Thank you for great videos.

[@floridian080]

A problem I've encountered is using a 2.8" TFT shield and separate SPI SD board with Arduino Due. The Due header is not accessible when shield is attached. Do you have a solution to this problem. Can MOSI, MISO and SCK be reassigned? Thanks for any help you can offer.

[@Sparky5]

I use the 4D systems touch screens with free Workshop 4 IDE software. Great for a non-programmer like myself.

[@danielbernhard1250]

Nice Video. How much overhead does it add to an existing sketch? I`m about to build a little project. I`ve got an interrupt pin used for calculating RPM out of a time (used 1 impuls per round on an gear-Motor between about 1 and 40 RPM). Then i use 4 digital pins for some buttons(wich i would exchange with the touchscreen). An other Pin is driving an PWN signal to the Gearmotor. 2 pins are used for relais for a heater and an cooling fan. An other pin drives a MOSFET to a little pump via AnalogWrite. An Steppermotor is driven (NEMA17) by using the millis() funktion to calculate the timing. I really like the idiea of having an touchscreen user interface. But if the stepper is running with about 20 RPM the cycles left for everything else, are decreasing a lot in order to have an accurate timing of the pulses. Next point is. I only have an Uno, Nano or an arduino Due. The due should be much more powerfull. But cause of the Cortex core, im worried about compatiblity issues with some libraries and the logical level of 3.3V.

[@TheElectronicDilettante]

Is it possible to add a diode, or some other device to isolate the pins) to pins 1 & 0 of the display pin out and still use 1&0 for serial communication??

[@tjmb71844]

I want to control 16 servos using a MEGA, and a PCA9865. I want to select the servo to be controlled using on-off switches and I want two LEDS per servo to show position. I also want to use a TFT 2.8 Display (not sure for what yet). Can you help me with a hook-up diagram? Also do I need a TFT sheild with the MEGA to get the 3V?

Hi I was wondering if someone could give me some advice. I have a system that uses a manual mixer value to supply water at a constant temperature to my gas boiler. I want to add an arduino that is controlled by a water thermostat and in turn controls a electronic valve of some kind. Also I would like to have a touchscreen connected to be able to set the temperature

[@BlueClefto]

Gramps is the best!

[@jaanbrosmusicofficial]

I'm trying to interact with an APP on my phone by indirectly touching the the screen. Modern touchscreens, as I'm sure everyone here knows are capacitive rather than resistive, so that means that I should be able to interact with it as long as I can bring a small current to the screen where I want to touch. I'm experimenting with using some speaker cable and a couple other wires I have laying around the house to see how far away I can be and still pass enough current through the wire to register a touch on the screen, based on my distance and the size and quality of the wire. What I'm finding though is that touching wire to the screen seems to register a touch even without me touching the wire. So is there already a current inside wire? Is it the type of wire I am using? I was under the impression that a wire on its own had no current and only passes electricity when there is an outside source. Is there anything I can do to decharge the wire, or block it somehow?

[@azv777]

Hello, thank you ! Great info as always, could you please prepare a video on how to make a display ESP to collect an information from other ESP devices, and how to pass this info to the cloud or google services, might be TUYA would be interesting too, Thanks again
