The project - replacing gauges in my truck with Arduino+TFT display. As a starter, I"m working strictly on single fuel gauge functionality, and eventually including dual fuel gauges (2 separate fuel tanks in truck), voltage gauge, coolant temp gauge, and GPS driven speedometer. Yeah...I"m already realizing I"m in for a bit of a steep learning curve here, lol.

The setup - Genuine Arduino Mega 2560, Seeed Studio 2.8" touchscreen sheild V1.0, aftermarket universal style fuel sender. Sender is connected to Analog pin 9 through a voltage divider circuit running roughly 1.5VDC-4.95VDC, and I get appropriate numbers from the serial monitor when cycling the sender. I"m not currently utilizing the touch features of the screen, though I may in the future. RIght now it"s strictly a display device. I did find out how to modify the TFT.h file to get the display to function on the Mega board, and am writing static text to it currently.

In this Arduino touch screen tutorial we will learn how to use TFT LCD Touch Screen with Arduino. You can watch the following video or read the written tutorial below.

As an example I am using a 3.2” TFT Touch Screen in a combination with a TFT LCD Arduino Mega Shield. We need a shield because the TFT Touch screen works at 3.3V and the Arduino Mega outputs are 5 V. For the first example I have the HC-SR04 ultrasonic sensor, then for the second example an RGB LED with three resistors and a push button for the game example. Also I had to make a custom made pin header like this, by soldering pin headers and bend on of them so I could insert them in between the Arduino Board and the TFT Shield.

Here’s the circuit schematic. We will use the GND pin, the digital pins from 8 to 13, as well as the pin number 14. As the 5V pins are already used by the TFT Screen I will use the pin number 13 as VCC, by setting it right away high in the setup section of code.

I will use the UTFT and URTouch libraries made by Henning Karlsen. Here I would like to say thanks to him for the incredible work he has done. The libraries enable really easy use of the TFT Screens, and they work with many different TFT screens sizes, shields and controllers. You can download these libraries from his website, RinkyDinkElectronics.com and also find a lot of demo examples and detailed documentation of how to use them.

After we include the libraries we need to create UTFT and URTouch objects. The parameters of these objects depends on the model of the TFT Screen and Shield and these details can be also found in the documentation of the libraries.

So now I will explain how we can make the home screen of the program. With the setBackColor() function we need to set the background color of the text, black one in our case. Then we need to set the color to white, set the big font and using the print() function, we will print the string “Arduino TFT Tutorial” at the center of the screen and 10 pixels  down the Y – Axis of the screen. Next we will set the color to red and draw the red line below the text. After that we need to set the color back to white, and print the two other strings, “by HowToMechatronics.com” using the small font and “Select Example” using the big font.

I gave up on the TFT Menu library when I was working on my project, there isn"t very good documentation except for the example and I only needed a single screen. Maybe I can answer a few questions from the code you posted:

I did a little experimenting with my TFT tonight. My current project has two joysticks attached to my Mega, so I just used these for test sensor values. If you just want to print out sensor values, here is an example sketch that displays time and pot values:

Hi, I have just received my 2.8inch TFT LCD shield purchased from Banggood, China. In the package there was just the TFT shield and packing...no paperwork or disc/files

So...my question for the forum is...How can I identify whether the problem lies with the TFT shield, the INO files and sketches that I am loading or is it something else.

ER-TFTM028-4 is 240x320 dots 2.8" color tft lcd module display with ILI9341 controller board,superior display quality,super wide viewing angle and easily controlled by MCU such as 8051, PIC, AVR, ARDUINO,ARM and Raspberry PI.It can be used in any embedded systems,industrial device,security and hand-held equipment which requires display in high quality and colorful image.

The 2.8″ TFT display used for this project comes as a shield with the form factor of the Arduino Uno. This makes it easy to connect the shield to boards like the Uno, Mega and Due, as all we need to do, is plug it directly into the board, eliminating all the mess made by wires.  Plug the display to the Arduino as shown in the image below.

The code for this tutorial is heavily reliant on a modified version of Adafruit’s TFT LCD,GFX and touchscreen libraries. These libraries can be downloaded from the links attached to them.

Next, we declare the colors to be used with their hexadecimal values and we create an object of the Adafruit TFTLCD library, indicating the variables used to represent the pins of the Arduino to which the display is connected.

We start by initializing the serial monitor and the display. After this, we set the orientation of the LCD and fill the screen with a black color to serve as the background.

The 2.8 inch TFT Touch Screen LCD Module For Arduino is a beautiful large touchscreen display shield with built in microSD card connection. The LCD has excellent vivid color contrast. This TFT display is big (2.8″ diagonal) bright (4 white-LED backlights) and colorful (18-bit 262,000 different shades). 240×320 pixels with individual pixel control. It has way more resolution than a black and white 128×64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.

After some more research & experimenting, I’m thinking the best solution is a hybrid panel. What I’ll do is use new 3.375" gauges for the speedometer & tachometer, the bikes’ original LCD for fuel, coolant temp, and gear position, and a 16x4 LCD for oil temp., oil pressure, volts, and air temp. I can use 18B20 sensors for the oil & air temp, I have a 5V oil pressure sensor that outputs volts from .5 to 4.5, and I’ve learned how to construct a voltage monitoring circuit. This avoids the headache of speedometer & odometer programming. Combining all of this into one sketch will be another learning experience.

I will be able to mount the LCD under an aluminum dash panel in a small plastic box with a Plexiglas cover & neoprene gasket to make it waterproof as much as possible. The bike will have a fairing with fuse panel, so I will likely mount the UNO in there out of the elements, maybe 2’ from the LCD. Worst case I could get a larger box & mount both under the dash panel.

I am making a small device that would be fitted on motorcycles. The device"s case will be a 3D printed case which houses a 2.2 inch SPI TFT display and a ESP32 module. I wanted to make the display waterproof so that it will keep working even in slight rain. I would be waterproofing ESP32 with sealing gel or epoxy. I just want a solution for the LCD display.

Look at your LCD display and tell me which side is waterproof. The front side. So, if your LCD is inside the box with only the glass front exposed, how is that NOT water proofed? Perhaps you need a rubber gasket between the glass front and your box.

Degreasing is critical, Tech Spray and others have electronic compatible degreasers. Check the specifications of your parts and make sure what you use is compatible. No LCD I’m aware if can take this unless it’s s specialty type.

Any component that is water sensitive such as LCD’s come with their own problems. Since ones pre-sealed against moisture are outrageously pricey you can build an enclosure just for them and seal that. It’s not hard, just tedious.

These appear to be bare-glass LCDs, so you will still need to drive them. An Arduino can produce the required 5VAC to drive them (DC will ruin an LCD), but if you multiplex the digits you shouldn"t need an obscene number of pins -- even an ATmega328/32u4 like the Uno/Nano/Micro/ProMini might have enough. You need 8 pins for the segments (or 7, if you never want to display the decimal point) plus 1 pin per digit, hopefully leaving just enough for Wifi/Ethernet/Bluetooth to grab the train times with.

It"s inconceivable that someone hasn"t already written an Arduino library for multiplexing bare-glass LCDs, but I didn"t find any with a quick Google?

I successfully built a project using 7 segment LED display, it works perfect! Very happy with the function of the code with LED display - the only problem is it"s not viewable outside where I plan on using it most of the time so after a ton of research it appears LCD 7 segment might be a good option, similar projects use this type of LCD display (if you have a better idea, I"d like to hear it and why it"d work well)

This project only needs to display numbers and the numbers are updated every 1 second. I think the static LCD will be perfect and it"s clearly viewable even in direct sunlight, I only need 3 segments and the LCD"s I currently have are Lumex 3 segment. My goal is to have nice large 3 digit numbers clearly displayed that can be read outside, the numbers will update in the code with millis() every second.

The issue I"m having transferring over my design to use a reflective static LCD - I can"t seem to find any information more than an explanation on the theory of how to correctly drive an LCD since it requires reversing polarity (AC) I have some ideas on how it might work and I"ve seen a proof of concept using XOR for one pin, driving the com pin and flipping the other pin with an XOR, the explanation I found basically ended there and left me with no practical idea where to start, I"m looking everywhere and can"t find anything on driving a static LCD with arduino so I"d appreciate any help pointing me in the right direction, I am completely stuck right now and would appreciate any help.

I have a mid 80’s Honda Sabre motorcycle, and the gauge panel is severely broken. I was able to salvage everything except the speedometer. The parts for it are no longer available, and used parts are sky high in cost when available, plus they’re 25 years old. The bike uses an electronic speedometer & tachometer, along with a digital display that had LCD gear positions (via 7 wires- one for each gear and neutral), fuel level, and water temperature. The bike predates the engine control modules and data bus setups of newer bikes- it’s fairly old school. The wheel speed sensor uses a three wire setup: an 8V input from the dash, sensor ground, and outputs 0~4 to 8V back to the gauge per the shop manual. I’ve looked at late model bike dashes, and many use CAN BUS setups that I’m unfamiliar with. Some older ones still uses similar sensor data as what mine does, so they are a possibility, but I’d have to add-on gauges to monitor all the things I want to monitor. I’ve looked at dashes (via wiring diagrams & shop manuals) from all the Japanese models as well as Aprilia, Buell, Ducati, and Triumph and even a couple of snowmobiles. All are either lacking a feature I want or they cost way too much. What I’d like to do is hijack a later model dash with an LCD panel & make it display the stuff I want… but I digress.

I found some LCDs with built-in serial graphics here. I downloaded the software tool and have been learning how to use it. Of course, I’d need either a waterproof LCD or secure casing for it/them. I have a basic understanding of electronics, and the ability to learn about things- I’ve self-taught myself things such as welding and AC repair.

I’d like to build an Arduino project to drive an LCD (or possibly 2, speed & RPM). What I’m planning to monitor is as follows, along with my comments:

I don’t need fancy displays on the LCD, just numbers & letters. I drew a prototype using some software and have attached a JPG of what I’d like to end up with (single screen).

You could do capacitive buttons, but a large amount of water on the face can cause problems. The advantage is that these too could be mounted to the back of a clear cover just like the LCD, so you"d need to make exactly 0 openings in the face of the enclosure.

Crystalfontz has a wide variety of LCD display products. Including ePaper, OLED, TFT and accessories. Watch our LCD videos below to see our display solutions in action.

This is a quick video showing our new 1.3 inch TFT LCD. This is a small, full-color TFT. It"s controlled via 4-wire SPI. It has a ST7789H2 controller. This display runs off a single 3.3v supply which controls the logic and backlight.

Check out this small, low power transflective LCD display. Available in many options including with and without a backlight, breakout board, or a complete development kit.

Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (5" diagonal) bright (18 white-LED backlight) and colorful 800x480 pixels with individual pixel control. As a bonus, this display has a capacitive touch panel attached on screen by default.

This TFT display is big 4"(3.97" diagonal) bright (6 white-LED backlight) and colorful (18-bit 262,000 different shades)! 480x800 pixels with individual pixel control. As a bonus, this display has a optional resistive touch panel with controller XPT2046 and capacitive touch panel with FT6336.

Displays are one of the best ways to provide feedback to users of a particular device or project and often the bigger the display, the better. For today’s tutorial, we will look on how to use the relatively big, low cost, ILI9481 based, 3.5″ Color TFT display with Arduino.

This 3.5″ color TFT display as mentioned above, is based on the ILI9481 TFT display driver. The module offers a resolution of 480×320 pixels and comes with an SD card slot through which an SD card loaded with graphics and UI can be attached to the display. The module is also pre-soldered with pins for easy mount (like a shield) on either of the Arduino Mega and Uno, which is nice since there are not many big TFT displays that work with the Arduino Uno.

To easily write code to use this display, we will use the GFX and TFT LCD libraries from “Adafruit” which can be downloaded here. With the library installed we can easily navigate through the examples that come with it and upload them to our setup to see the display in action. By studying these examples, one could easily learn how to use this display. However, I have compiled some of the most important functions for the display of text and graphics into an Arduino sketch for the sake of this tutorial. The complete sketch is attached in a zip file under the download section of this tutorial.

As usual, we will do a quick run through of the code and we start by including the libraries which we will use for the project, in this case, the Adafruit GFX and TFT LCD libraries.

With this done, the Void Setup() function is next. We start the function by issuing atft.reset() command to reset the LCD to default configurations. Next, we specify the type of the LCD we are using via the LCD.begin function and set the rotation of the TFT as desired. We proceed to fill the screen with different colors and display different kind of text using diverse color (via the tft.SetTextColor() function) and font size (via the tft.setTextSize() function).

Alibaba.com offers 411 arduino tft screen products. About 58% % of these are lcd modules, 20%% are lcd touch screen, and 4%% are integrated circuits （old）.

The screen is 1.77" diagonal, with 160 x 128 pixel resolution. The TFT library interfaces with the screen"s controller through SPI when using the TFT library. Refer to the screen"s data sheet for complete details.

The Arduino TFT library extends the Adafruit GFX, and Adafruit ST7735 libraries that it is based on. The GFX library is responsible for the drawing routines, while the ST7735 library is specific to the screen on the Arduino screen. The Arduino specific additions were designed to work as similarly to the Processing API as possible.

The TFT library relies on the SPI library, which must be included in any sketch that uses the scree. If you wish to use the SD card, you need to include the SD library as well.

This module is designed to plug directly into Arduino UNO R3 (or its clone) boards. It is compatible with CH340 and Atmega16u2 version boards, as well as Mega 2560. This LCD shield may also work with other boards, but the compatibility can"t be guaranteed.
