Currently I have code to swipe in rfid tags to a reader which then using the arduino Uno it lights up an LED coordinating to which tag was swiped. What I"m looking to do now is set a dollar amount to each tag and once a tag is swiped in add it to like a current total price and then output that to LCD Screen. Is this possible with Arduino Uno? Anyone help with this?

Although some displays have a built-in resistor to limit the supply current to the backlighting diodes, it is worth using an external limiter. In this case, the 5V line is connected via a 200 ohm resistor.

The display is an important tool in the process of communication between an electronic device and a person. It is useful for detecting errors during testing or viewing data collected by the microcontroller. Together with the buttons it forms the basis of the user interface.

Alphanumeric modules based on the HD44780 controller are extremely easy to use. When there is no need to display graphics, these devices perform very well and are eagerly used by hobbyists and professionals.

In this guide we’re going to show you how you can use the 1.8 TFT display with the Arduino. You’ll learn how to wire the display, write text, draw shapes and display images on the screen.

The 1.8 TFT is a colorful display with 128 x 160 color pixels. The display can load images from an SD card – it has an SD card slot at the back. The following figure shows the screen front and back view.

This module uses SPI communication – see the wiring below . To control the display we’ll use the TFT library, which is already included with Arduino IDE 1.0.5 and later.

The TFT display communicates with the Arduino via SPI communication, so you need to include the SPI library on your code. We also use the TFT library to write and draw on the display.

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.

The 1.8 TFT display can load images from the SD card. To read from the SD card you use the SD library, already included in the Arduino IDE software. Follow the next steps to display an image on the display:

Note: some people find issues with this display when trying to read from the SD card. We don’t know why that happens. In fact, we tested a couple of times and it worked well, and then, when we were about to record to show you the final result, the display didn’t recognized the SD card anymore – we’re not sure if it’s a problem with the SD card holder that doesn’t establish a proper connection with the SD card. However, we are sure these instructions work, because we’ve tested them.

In this guide we’ve shown you how to use the 1.8 TFT display with the Arduino: display text, draw shapes and display images. You can easily add a nice visual interface to your projects using this display.

Before Executing Install the packages and Enter the Arduino Port NoMake Sure"INTERNET IS TURNED ON"Now run the python fileNow you can see output in the LCD display
