To read from the SD card you use the SD library, already included in the Arduino IDE software. The 1.8 TFT display can load images from the SD card. Here’s the shapes on the display: Display images wait 200 miliseconds until change to next figure

Every time the code goes through the loop, the shapes change color. The following example displays several shapes. circle(x, y, radius) – draws a circle with center at (x, y) with the specified radius rect(xStart, yStart, width, height) – draws a rectangle with the top left corner at (xStart, yStart) with the defined width and height line(xStart, yStart, 圎nd, yEnd) – draws a line that starts at (xStart, yStart) and ends at (圎nd, yEnd) point(x, y) – display a point at the (x, y) coordinate The TFT library provides useful functions to draw shapes on the display: Here’s your “Hello, World!” text on the 1.8 TFT display. wait 200 miliseconds until change to next color

print Hello, World! in the middle of the screen TFTscreen.stroke(redRandom, greenRandom, blueRandom) clear the screen with a black background The following example displays “Hello, World!” in the middle of the screen and changes the font color every 200 miliseconds.Ĭopy the following code to your Arduino IDE and upload it to your Arduino board. In which “ Hello, World!” is the text you want to display and the (x, y) coordinate is the location where you want to start display text on the screen. You can increase or decrease the number given as argument, to increase or decrease font size.įinally, to draw text on the display you use the following line: TFTscreen.text(' Hello, World!', x, y)

To choose font color: TFTscreen.stroke( r, g, b) In which, r, g and b are the RGB values for a given color. To set the background color, use: TFTscreen.background( r, g, b) To write text on the display, you can customize the screen background color, font size and color. Then, you need to define the CS, A0 (or DC) and RST pins: #define cs 10 #define dc 9 #define rst 8Ĭreate an instance of the library called TFTscreen: TFT TFTscreen = TFT(cs, dc, rst) įinally, in the setup(), you need to initialize the library: TFTscreen.begin() Display text We also use the TFT library to write and draw on the display. The TFT display communicates with the Arduino via SPI communication, so you need to include the SPI library on your code. If you’re using another Arduino board, check the Arduino official documentation.

Note: different Arduino boards have different SPI pins. The table below shows the 1.8 TFT wiring to Arduino UNO. You can use the preceding links or go directly to /tools to find all the parts for your projects at the best price! You can get the 1.8 TFT display for approximately $3 – check prices on Maker Advisor. To control the display we’ll use the TFT library, which is already included with Arduino IDE 1.0.5 and later. This module uses SPI communication – see the wiring below. The following figure shows the screen front and back view. The display can load images from an SD card – it has an SD card slot at the back. The 1.8 TFT is a colorful display with 128 x 160 color pixels.

You’ll learn how to wire the display, write text, draw shapes and display images on the screen. V1.In this guide we’re going to show you how you can use the 1.8 TFT display with the Arduino. The arduino nano shield has independent power supply to provide extra power for servo and other sensors.

The board also has a space specifically for the DFRobot bluetooth module and ACP220. To the best compatibility, the shield supports jumper wires for rapid prototyping. In addition, the sensor shield adopts Gravity interface that each pinout includes 5V and GND pins for easy connection to Gravity sensors or servos. The form factor of the Nano I/O Shield board is the same as the Arduino UNO/ arduino Leonardo. There are several different options for power input. The Arduino Nano I/O Sensor Shield acts as an expansion board for the Arduino Nano and DFRduino Nano microcontrollers.
