adafruit.com has lots of 2.8″ TFT breakouts in stock and a brand new tutorial for drawing bitmaps of any size from SD storage!
We have an example sketch in the library showing how to display full color bitmap images stored on an SD card. You’ll need an SD or microSD breakout board such as this one . You’ll also need to download our SD library modifyied to allow faster reads (these changes will be added to arduino v23) but for now you can download the new library here . Download the library by clicking the Downloads button and uncompressing the folder. Replace the files in your ArduinoIDE/libraries/SD folder and restart the IDE.

The Computerless Arduino consists of two major components; an Arduino-compatible microcontroller loaded with a realtime code interpreter, and a stand-alone 5-button LCD display to display port values and manipulate code. The display can be connected to the Arduino via a 4-pin port at any time to peek at In/Out values, view the current code, and make changes as desired.

I recently obtained a very old mobile phone from a friend. The battery was dead, so I dismantled it and to my surprise found a display with soldered contacts. In other mobile phones the display was connected via a conducting polymerpad, which was extremly difficult to use on selfmade circuitboards.

This tutorial shows how to use the advanced functionality of HD44780 16×2 LCD’s where you can create your own characters instead of using the built-in character set. It also gives a simple demonstration of animation on the LCD module.

LCD displays of the 2×16 variety are a good way of getting feedback from your Arduino project. If you want a more enhanced visual experience, a thin-film transistor (TFT) LCD is the superior way to go. This tutorial by Tronixstuff describes a way use the the 4D Systems 1.44″ TFT serial interface LCD with Arduino. [via]

Markus demonstrates his OLED display sine-scroller:
The OLED board sold by SeeedStudio used I2C to communicate with the MCU. I found that updating the screen this way takes too long to get a descent refresh rate, so I modified the board to be able to access the driver chip using its SPI interface.
Updating the whole screen (128 x 64 pixel = 1024 Byte) takes now only about 1 ms, giving enough time to do some other fun stuff between updates

Reverse Engineering is an important skill for electronics hobbyists because very often you will run into something you want to use, but don’t know how. An LCD is a tough thing to reverse engineer, but this tutorial shows you one approach to figuring out how to get things working. [via]

This project describes how to measure temperature with Atmega8 and a thermistor and display it on a Nokia 3310 LCD. A thermistor is a device that changes its resistance with temperature. With a proper resistor divider network, the temperature can be measured by measuring the voltage across the thermistor. [via]
