Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (9" diagonal) bright (30 white-LED backlight) and colorfu 800x480 pixels with individual pixel control. As a bonus, this display has a optional capacitive and resistive touch panel attached on screen by default.

The shield is fully assembled, tested and ready to go. No wiring, no soldering! Simply plug it in and load up our library - you"ll have it running in under 10 minutes! Works best with any classic Arduino (UNO/Due/Mega 2560).

This display shield has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. You can connect more sensors, buttons and LEDs.

Of course, we wouldn"t just leave you with a datasheet and a "good luck!" - we"ve written a full open source graphics library at the bottom of this page that can draw pixels, lines, rectangles, circles and text. We also have a touch screen library that detects x,y and z (pressure) and example code to demonstrate all of it. The code is written for Arduino but can be easily ported to your favorite microcontroller!

For 9 inch screen,the high current is needed.But the current of arduino uno or arduino mega board is low, an external 5V power supply is needed. Refer to the image shows the external power supply position on shield ER-AS-RA8875.

If you"ve had a lot of Arduino DUEs go through your hands (or if you are just unlucky), chances are you’ve come across at least one that does not start-up properly.The symptom is simple: you power up the Arduino but it doesn’t appear to “boot”. Your code simply doesn"t start running.You might have noticed that resetting the board (by pressing the reset button) causes the board to start-up normally.The fix is simple,here is the solution.

This is a very popular LCD Keypad shield for Arduino or Freeduino board. It includes a 2x16 LCD display and 6 momentary push buttons. Pins 4, 5, 6, 7, 8, 9 and 10 are used to interface with the LCD. Analog Pin 0 is used to read the push buttons. The LCD shield supports contrast adjustment and backlit on/off functions. It also expands analog pins for easy analog sensor reading and display.

The LCD Keypad shield is developed for Arduino compatible boards, to provide a user-friendly interface that allows users to go through the menu, make selections etc. It consists of a 1602 white character blue backlight LCD. The keypad consists of 5 keys — select, up, right, down and left. To save the digital IO pins, the keypad interface uses only one ADC channel. The key value is read through a 5 stage voltage divider.

Creates a variable of type LiquidCrystal. The display can be controlled using 4 or 8 data lines. If the former, omit the pin numbers for d0 to d3 and leave those lines unconnected. The RW pin can be tied to ground instead of connected to a pin on the Arduino; if so, omit it from this function"s parameters. for example:

Initializes the interface to the LCD screen, and specifies the dimensions (width and height) of the display. begin() needs to be called before any other LCD library commands.for example:

The J1-J8 include the both the user interface, i.e. Analog pins, APC220(Serial) pins, Digital pins, and the pins connected with the lower Arduino card, e.g. Uno/ Leonardo. Here is a simple mapping picture.

It works well if uploaded by Arduino 1.5.3 version, however, the latest 1.6.* have discard pin Definition for Edison. So you have to add pinMode(); into the setup() like this:

Let"s get started with this creative Arduino project, where you"ll learn about the TFT LCD touch screen and how to use it to create your own colourful calculator. For a basic understanding of touch screen & LCD, a cheap TFT 2.4" Arduino shield is used to create this project. For creating a similar project, one should follow the steps and edit the code for better understanding.

Touch-screen devices using resistive technology, a two-dimensional membrane potentiometer provides x and y coordinates. The top layer is thin glass spaced close to a neighboring inner layer. The underside of the top layer has a transparent conductive coating; the surface of the layer beneath it has a transparent resistive coating. A finger or stylus deforms the glass to contact the underlying layer. Edges of the resistive layer have conductive contacts. Locating the contact point is done by applying a voltage to opposite edges, leaving the other two edges temporarily unconnected. The voltage of the top layer provides one coordinate. Disconnecting those two edges, and applying a voltage to the other two, formerly unconnected, provides the other coordinate. Alternating rapidly between pairs of edges provides frequent position updates. An analog to digital converter provides output data.

The shield connects ILI9341"s data pins 0-7 to Arduino"s digital pins 2-8 (allowing parallel communication, not SPI. ILI9341"s RESET goes to Arduino analog pin A4. CS (chip select) to A3. RS (CD command/data) to A2. WR and RD to A1 and A0.

ILI9341 is integrated inside the display. It drives the display and has nothing to do with the touchscreen (Although the shield connects some pins of ILI9341 together with pins of the touchscreen).

first, you have to send a command to ILI9341 and then write or read data/parameters. CS pin has to be LOW during the communication, WR rising from LOW to HIGH tells ILI9341 to read byte on data pins.ILI9341 interprets input byte as a command (if RS=0) or as data/parameter (RS=1).

To read a byte from ILI9341 after sending a read command (e.g. 09h - Read Display Status) set RD from HIGH to LOW, so ILI9341 outputs data until RD returns HIGH.

To install this library, you can simply click on the link above which will take you to a Github page. There click on clone or download and select “Download ZIP”. A zip file will be downloaded.

Now, open Arduino IDE and select Sketch -> Include Library -> Add .ZIP library. A browser window will open navigate to the ZIP file and click “OK”. You should notice “Library added to your Libraries” on the bottom-left corner of Arduino, if successful.

The touchscreen I tested sometimes wrongly detects a touch, outside of the touched point. To prevent this I added some delays and the X and Y analog value is read repeatedly and touch is approved only if values do not differ a lot.

You can also find an SD card slot at the bottom of the module shown above, which can be used to load an SD card with BMP image files, and these images can be displayed on our TFT LCD screen using the Arduino Program.

The 2.4” TFT LCD screen is a perfect Arduino Shield. You can directly push the LCD screen on top of the Arduino Uno and it will perfectly match with the pins and slid in through. However, as matters of safety cover the programming terminal of your Arduino UNO with some insulator, just in case if the terminal comes in contact with your TFT LCD screen.

The calculator here is based on the simple logic that, you have to divide the screen according to touch coordinates values and write a program accordingly. Every digit or symbol visible on-screen have a defined area.

This is SainSmart UNO R3 and 2.8 inch TFT LCD module with the TFT LCD shield kit For arduino enthusiasts.It includes one pcs of sainsmart UNO R3, one pcs of 2.8 inch TFT LCD display and a TFT LCD shield. We will provided you the whole document including the example project of arduino UNO(R3) with the kit. We will supply you the technical support after your purchase.

The SainSmart Uno R3 is a microcontroller board based on the ATmega328 . It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible with both the board that uses the AVR, which operates with 5V and with the Sainsmart Due that operates with 3.3V. The second one is a not connected pin, that is reserved for future purposes.

SainSmart 2.8" TFT LCD Display is a LCD touch screen module. It has 40pins interface and SD card and Flash reader design. It is a powerful and mutilfunctional module for your project.The Screen include a controller ILI9325, it"s a support 8/16bit data interface , easy to drive by many MCU like arduino families,STM32 ,AVR and 8051. It is designed with a touch controller in it . The touch IC is XPT2046 , and touch interface is included in the 40 pins breakout. It is the version of product only with touch screen and touch controller.

Voltage type: 5v or 3v voltage input voltage,input is selectable. Because TFT can only work under 3.3 V voltage, so when the input voltage VIN is 5V, need through the 3.3 V voltage regulator IC step down to 3.3V , when the input voltage of 3.3 V, you need to use the zero resistance make J2 short , is equivalent to not through the voltage regulator IC for module and power supply directly.

This is SainSmart TFT LCD Extend shield for UNO(R3) .Using this shield can help you out of the bothers to use other cables. You just need to plug the module to arduino UNO(R3) through this shield.

If you connect the touch screen LCD with UNO R3, the touch screen function will be useless . If you want to use the touch function, please connect the LCD with Mega2560 (R3) or Due (R3).

2.The LCD is compatible for arduino family,but the Shield is just for the arduino UNO R3. If you need the LCD Extend shield for other arduinos, you need another shield which is also provided from our store.

Modular designs are always easy to develop & scale, and this also applies to electronics. Since Arduino is the go-to microcontroller for circuit prototyping and development, it is necessary to have additional modules that increase functionality to create customized projects. That is where Arduino Shields come in.

They are small boards that connect and stack onto the Arduino board to provide specific functions. If you have a project in development, here"s a close look at these modules, including a list of the compatible ones for different projects.

Arduino shields are plug-in or add-on boards attached to an Arduino board to provide extra functionalities. They have a similar pin position to the Arduino board and usually perform a specific function, such as communication or running a motor.

Arduino boards make it easy to play around with electrical components, placing them on a breadboard for easy connection. However, you should not assemble the final product with an external breadboard. It is neat and more professional to use expansion boards like Arduino Shields to set up the complete project.

Each Arduino shield must have a similar pin position and form factor as a standard Arduino board. Therefore, the power and ground pins should be on one 8-pin header, while the analog pins should be on one 6-pin header.

The digital pins should be on the opposite side of the analog pins on an 8-pin header. A 0.5-inch spacing should separate these from the rest of the digital and I2C interface pins. Some shields have extra pins to connect to the ICSP 2 x 3 programming header pins.

But not all Arduino boards have the same pin layout. For instance, Arduino UNO and MEGA are different. Therefore, you should choose a compatible board by looking at three factors.

Also, it is worth noting that not all shields require a link to every pin. Some use the serial, I2C, analog, or SPI pins to communicate with the Arduino PCB. You can have a stackable shield set up with as many shields as possible connected to one Arduino PCB, but don"t use overlapping pins.

The prototyping shield is one of the most uncomplicated Arduino shields because it features a prototyping area for soldering components. If soldering is too much work, you can attach the included 170-pin mini breadboard to the prototyping area.

An Arduino motor shield is critical for building RC cars and robots. There are several types, but the most popular one is the L293D, and it contains a 74HC595 Shift Register IC plus two L239D integrated circuits. It can power four 12V DC motors and two servo or stepper motors simultaneously.

As the name suggests, the purpose of this shield is to control devices like RC cars and robots using joysticks. Like the motor shield, this one is available in several varieties.

A relay shield is a module used to control devices powered by the mains AC power line. It contains four mechanical relay power modules (each with a dedicated terminal connector) and four LEDs to indicate the relay"s state (NC or NO).

With a row and column matrix keypad, this shield has 16 buttons that you can map to different characters for input. Also, it features a dedicated header for connecting the LCD module of a Nokia 5110.

If you prefer a touchpad interface instead of keys, you can incorporate the capacitive touchpad shield into your Arduino project. It contains nine capacitive touchpads and a proximity sensor controller.

If you need several servo motors for a Hexapod robot or robotic arm, consider using this 16-channel, 12-PWM servo motor shield. It can also power LEDs using PWM signals.

If your Arduino project involves sending or receiving SMS messages, making or answering calls, and connecting to the internet via GPRS, you need to use a GSM/GPRS shield.

Some shields have Bluetooth modules for wireless communication over the serial interface, but you can get a single module for this function. You can control the board using AT commands, and some allow firmware flashing for feature updates. An example is the HC-05.

Even though most internet communications happen over WiFi, ethernet is still widely used, primarily for its high speeds. An ethernet shield can reach speeds of up to 100Mbps and features an RJ-45 jack for the ethernet cable.

WiFi shields like the ESP8266 are essential components in IoT projects because they provide wireless internet connectivity to Arduino PCBs. The module also features a microSD card slot, and it plugs into Arduino boards, eliminating the need for breadboarding or soldering.

An MP3 player music shield, like the VS1053 decoder IC, enables you to add high-quality audio to your electronic project. It can decode MP3, AAC, MIDI, WMA, & Ogg Vorbis audio formats and features a microSD card slot to store the music. Also, it has a 3.5mm headphone jack.

With the ST7735 TFT Driver IC controller, this shield displays 18-bit colors in a 160x128-pixel, 1.8-inch TFT LCD. The board also contains a 5-way navigation module and a microSD card slot.

Touchscreens are popular input/output interfaces, and you can incorporate this shield into your project to include this functionality. You can get the screen in various sizes, but the 2.4-inch LCD is the most sought-after. It has a 320x240 pixel resolution and features a microSD card slot.

Several shields have microSD card slots, but if you need a dedicated one for applications like data logging, use the microSD module. It supports FAT FS implementation of FAT libraries and communicates with Arduino via SPI.

Designed around the MCP2515 CAN bus controller, this shield is ideal for low-speed, long-distance data transfer. It requires a CAN transceiver for single-ended to differential data line conversion and features an SPI interface.

This shield simplifies the process of adding Xbee modules to your project. It supports multiple wireless networks, such as Bluetooth Low Energy and Zigbee. These make it an ideal choice for working on wireless projects like data transfer apps.

A GPS shield consists of a GPS receiver module and a microSD card slot for data logging. It exchanges data with the Arduino board over serial communication, while the SD card connects via SPI communication.

As the name suggests, this shield adds NFC and RFID functionality (13.57MHz) to your project. It has an internal & external antenna that you can select optionally using jumpers. The board is compatible with I2C, SPI, and SPI communication interfaces.

Based on the MAX3421 USB host/ peripheral controller (with SPI interface), this shield contains all the analog and digital circuitry required for full-speed USB connectivity to your Arduino UNO.

Smoke sensors are essential for safety applications, and this shield is ideal for adding LPG, carbon monoxide, smoke, and other toxic gas detection capabilities to your project.

An RS485 shield gives galvanic isolation between its bus and the Arduino board to prevent noise and interference. The device supports 2-wire (half-duplex) and 4-wire (full-duplex) data transfer and bases its design on the ISO3080, a completely isolated RS485 transceiver.

If you want to add RGB LEDs to your project, consider using the NeoPixel shield. The Adafruit extension board bases its design on the WS2812B. It has 40 RGB LEDs in an 8x5 matrix, and each is fully customizable.

Not many devices use the MIDI communication protocol, but this shield is still ideal for controlling music samplers, synthesizers, sequencers, and more using Arduino. It creates a MIDI interface system with MIDI in & out ports and contains two configurable potentiometers for pitch, volume, and tone control.

If you are developing a power-sensitive project, get an energy shield. It contains a LiPo battery that can power the Arduino or Arduino-compatible board when the external power supply goes off. The battery charges when power is available and then switches to become the power source when the power supply goes off.

Last on the list is the camera shield. It provides a simple UI and an easy-to-use camera and connects to Arduino via SPI. The unit consists of a 3.2-inch touchscreen plus a microSD card slot.

In conclusion, Arduino shields are essential for Arduino projects because most Arduino boards are pretty basic. Plugging in these shields provides the features required to make your project a success. If you have any questions about these modules, reach out for further clarification.
