arduino lcd module sd card reader in stock
Description: The Arduino Graphic LCD (GLCD) screen is a backlit TFT LCD screen with headers. You can draw text, images, and shapes to the screen with the GLCD library. There is an onboard micro-SD card slot on the back of the screen that can, among other things, store bitmap images for the screen to display.
The screen"s headers are designed to fit into the socket on the front of the Arduino Esplora, but it is compatible with any AVR-based Arduino (Uno, Leonardo, etc. Datasheet You can use this module with Arduino Esplora.

Key Features: Use this small LCD screen with Arduino Robot, Esplora, or on breadboard. The screen is 1.77" diagonal, with 160 x 128 pixel resolution. Includes micro-sD socket The LED backlight is dimmable by PWM. The screen" s headers are laid out so it easily sockets into the Arduino Esplora and Arduino Robot.

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.
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.
NoteThese 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.
What’s Next?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)
This example shows how to read and write data to and from an SD card.In setup(), create a new file with SD.open() named "test.txt". FILE_WRITE enables read and write access to the file, starting at the end. If a file "test.txt" was already on the card, that file would be opened.
Again, open the file with SD.open(). Once opened, ask the Arduino to read the contents of the file with SD.read() and send them over the serial port. After all the contents of the file are read, close the file with SD.close().
Note that pin 4 is default Chip Select (CS) pin for most boards. To set CS for MKR Zero, you can use 28 instead of 4, alt. use the SDCARD_SS_PIN definition.
This example shows how to read information about a SD card. The example reports volume type, free space and other information using the SD library, sending it over the serial port.
On the SD card, there is a file named "datalog.txt". In theloop(), the file is opened when calling SD.open(). To send the file serially to a computer, use Serial.print(), reading the contents of the file with SD.read().
In thesetup(), open a new file with SD.open() named "example.txt". FILE_WRITE enables read and write access to the file, starting at the end. In this example though, immediately close the file by calling myFile.close().
The mainloop() does nothing because the function that prints out the file directory of "/" of the SD card is called from the setup(). This because we need to see it just once.

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.

In this tutorial, you’ll learn how to use SD and micro SD cards with Arduino. In the end, as a simple project, you will measure the environment temperature every hour and store it on the SD card.
