lcd module sd card reader arduino in stock

I am trying to make a truly Universal Remote Control out of this mess. I just got the Arduino Uno & the Display and put it together and there are NO pins left to operate an IR LED.

Can you elaborate on which libraries will work, I"ve been fighting with this thing since I got it. I need it to play a simple video if possible. I"m trying to help an elderly lady in her 80s be able to watch videos from the SD card. Any help would be greatly appreciated. It"s for a very good cause.0

Can this 2.8" elegoo display play video at all? I"m trying to make a unit that an older woman, in her 80"s can play a video on it, if I set it up correctly? This is for a really good cause, I desperately need help, this is super important. Helping elderly folks with modern technology is tough. But I really need it to be able to play a video off the SD card if possible. Any help would be super highly appreciated.ReplyUpvote

Hello,please post our code also ..the screen driver must be known and that info must be known in order to get these things to work correctly..you show your code and then the vid blurs..Someone needs to write a pdf teaching how ,what ,when and why concerning these screens I would gladly pay $10.00 and I am sure others would too.I have 3 different tftlcds only 1 works its for the mega and Bomer has a lib for it,I am really considering use of Nextion units from now on 4 pins easy programming but higher cost...also the small cell phone screens use spi mode and are real easy to set up and use

The program runs and nothing is displayed but a white screen. when I open the COM4 I see that when I hit the screen numbers appear to calibrate the screens position so it is registering but not showing up on the LCD. please help me before I pull all my hair out.1

I"m thinking I need an Arduino Mega to do what I want - a Universal Remote. Because after mounting the display there are NO pins left for anything else.0

I"m having issues getting this display to work on my Arduino 101 board with the libraries that are suggested - errors in compiling seem to indicate that the board type isn"t supported in the Adafruit_TFTLCD library. Here"s a representative error:

I finally got the touchscreen to work correct using your links to the libraries. Found out that this specific TFT display module uses pin 6 & 7 for touch sensor, instead of the standard 4 & 5.0

I never received a response on this, so went through the painful process of copying code from the video. It can be found here for others that might need it. Not that this has some minor changes, but is fully functional and I will continue to refine: https://github.com/siliconghost/Arduino_2.8in_TFT_wSD

The Arduino TFT screen is a backlit LCD screen with headers. You can draw text, images, and shapes to the screen with the TFT library. There is an onboard micro-SD card slot on the back of the screen that can store bitmap images to be displayed.

The screen"s headers are designed to fit into the socket on the front of the Arduino Esplora; also it is compatible with any AVR-based Arduino (arduino Uno, arduino Leonardo, etc) or with the Arduino Due. If you want to connect the screen with other Arduino boards, read the tutorial on this link.

A micro sd card module is preferred in cases you need to store large amounts of data and other information for your Arduino project. The EEPROM of the Arduino microcontroller has a limited storage capacity and is specific with the format and nature of data it can hold. This makes it not the best for storing data like text, CSV, audio, video or image files.

A 74LVC125A Level Shifter on the module converts the interface logic from 3.3V-5V to 3.3V. This enables us to use this device with both 3.3V and 5V microcontrollers like Arduino.

Before inserting the micro SD card into the module and hooking it up to the Arduino, make sure it is properly formatted and is using the FAT16 or FAT32 file system. Most new SD cards come when already pre-formatted with a FAT file system but it’s always good to do it yourself to be certain.

The SD card module uses the SPI communication protocol and is therefore connected to the Arduino hardware SPI pins. The SPI pins depend on the type of Arduino used but in this case we are using the UNO whose SPI pins are from pin 10 to 12.

The connections are done as shown below. Make sure you don’t change the order of connection for the SCK, MOSI and MISO pins because they are declared in that order within the SD.h library.

The CardInfo sketch will not write any data to the card but it tells you if the card is recognized and also displays some information about it. This information is shown in the serial monitor like shown below.

After running the CardInfo sketch, you can run other sketches like the ReadWrite sketch so that you can learn how to use the various functions for reading and writing data to the SD card.

After setting up the micro SD card module for use with Arduino, we can now be able to store data like images in the sd card and display them on a TFT LCD screen. The best images to display are bitmap images so make sure you convert your images to bitmap format before storing them into the SD card. You can use an online image convertor.

This SD Card Breakout Module allows you to read directly off an SD Card and into your microcontrollers such as Arduino & Raspberry Pi. The data is easily accessable via microcontroller using the popular SPI protocol.

Note: If you have trouble with a certain SD card, try another card because some low quality cards may cause problems when trying to read / write data to and from Arduino.

This project uses an SD card breakout board to allow for the reading of a.txt file with an Arduino Nano. The Arduino can then display the contents of the text file on a liquid crystal display.

First, we need to create a text file on a micro sd card that the Arduino will read. Insert the card in your computer (you may need an adapter for this if your computer doesn"t already have a microSD slot, I included a link to one above).Once the card is in your computer, navigate to its folder:This PC>cardname

Create a circuit as shown in the above diagram. If you choose to use another Arduino board instead, such as an UNO, all of the pins used will be the same.

This project is really meant to be an example of how to use an SD card with Arduino. If you are looking for more code examples or uses, here are some other sites you can visit:

Storing data is one of the most important parts of every project. There are several ways to store data according to the data type and size. SD and micro SD cards are one of the most practical ones among the storage devices, which are used in devices such as mobile phones, minicomputers and etc.

The SD and micro SD card modules allow you to communicate with the memory card and write or read the information on them. The module interfaces in the SPI protocol.

These modules can not handle high-capacity memory cards. Usually, the maximum identifiable capacity of these modules is 2GB for SD cards, and 16GB for micro SD cards.

Opens a file on the SD card in reading or writing mode. (If you leave the mode section blank, the file will open in reading mode by default) If the file is opened for writing, it will be created a file with this name if it doesn’t already exist.

Create an entry/exit control device. Using the RFID module and Arduino, save entrance and exit time for several persons on the memory card. (Consider an RFID card for each person)
