rePaper eInk Development Board

Daylight Readable Graphical eInk Displays

Learn how to assemble and program the RePaper eInk Development Board. These daylight readable displays are excellent for data-logging applications, outdoor displays, or any other ultra-low power project.

USB + Serial RGB Backlight Character LCD Backpack

Control an RGB Character LCD with USB or TTL Serial

Adding a character display to your project or computer has never been easier with the new Adafruit USB or TTL serial backpack! This custom-designed PCB sits on the back of any 'standard' character LCD (16x2 or 20x4 sized) and does everything you could want: printing text, automatic scrolling, setting the backlight, adjusting contrast, making custom characters, turning on and off the cursor, etc. It can even handle our RGB backlight LCDs with full 8-bit PWM control of the backlight.

2.8" TFT Touchscreen

320x240 pixels in 16 bit color with a touchscreen

Add some jazz & pizazz to your project with a color touchscreen LCD. This TFT display is big (2.8" diagonal) bright (4 white-LED backlight) and colorful (16-bit 262,000 different shades)! 240x320 pixels with individual pixel control, this has way more resolution than a black and white 128x64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen. Learn how to use this LCD with an Arduino.

Nokia 5110/3310 Monochrome LCD

A guide to using our small Nokia 5110/3310 LCD w/backlight

This is a quick tutorial for our 84x48 pixel monochrome LCD display. These displays are small, only about 1.5" diameter, but very readable due and comes with a backlight. This display is made of 84x48 individual pixels, so you can use it for graphics, text or bitmaps. These displays are inexpensive, easy to use, require only a few digital I/O pins and are fairly low power as well.

OLED TRON Clock

Display the current time in style.

Use an OLED display, an RTC, and an Arduino to build a TRON style clock.

2.8" TFT Touch Shield

320x240 pixels in 16 bit color with a touchscreen for your Arduino

Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (2.8" diagonal) bright (4 white-LED backlight) and colorful (18-bit 262,000 different shades)! 240x320 pixels with individual pixel control. It has way more resolution than a black and white 128x64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen. This tutorial will teach you how to use this shield with your Arduino.

Arduino "Hunt The Wumpus"

Play Hunt the Wumpus on an Arduino

Use Adafruit's RGB LCD shield and an Arduino to revisit the early days of computer gaming. You too can hunt the Wumpus or, perhaps, be eaten by the Wumpus.

2.2" TFT Display

220x176 pixels in 18 bit color with a microSD breakout

This lovely little display breakout is the best way to add a small, colorful and bright display to any project. Since the display uses 3-wire SPI to communicate and has its own pixel-addressable frame buffer, it can be used with every kind of microcontroller. Even a very small one with low memory and few pins available!

1.8" TFT Display Breakout and Shield

128x160 pixels in 18 bit color with a microSD

This tutorial is for our 1.8" diagonal TFT display & microSD in both the shield and breakout board configurations. These displays are a great way to add a small, colorful and bright display to any project. Since the display uses 4-wire SPI to communicate and has its own pixel-addressable frame buffer, it can be used with every kind of microcontroller. Even a very small one with low memory and few pins available!

i2c/SPI LCD Backpack

Saving you 4 pins, every day

LCDs are a fun and easy way to have your microcontroller project talk back to you. We wanted to make a 'backpack' (add-on circuit) that would reduce the number of pins without a lot of expense. By using simple i2c and SPI input/output expanders we have reduced the number of pins (only 2 pins are needed for i2c) while still making it easy to interface with the LCD.

Monochrome OLED Breakouts

Using our small mono-OLED displays

This is a quick tutorial for our 128x64 and 128x32 pixel monochrome OLED displays. These displays are small, only about 1" diameter, but very readable due to the high contrast of an OLED display. Each OLED display is made of 128x64 or 128x32 individual white OLEDs, each one is turned on or off by the controller chip. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast; we really like this miniature display for its crispness!

Character LCDs

Wiring up a character LCD to an Arduino

We sell tons of lovely character LCDs for use with Arduino, they are extremely common and a fast way to have your project show status messages. This tutorial will show how you can easily connect a character LCD, either 16x2 or 20x4.

0.96" mini Color OLED

Mini color OLED displays

Our 0.96" color OLED displays are perfect when you need an ultra-small display with vivid, high-contrast 16-bit color. The visible portion of the OLED measures 0.96" diagonal and contains 96x64 RGB pixels, each one made of red, green and blue OLEDs. Each pixel can be set with 16-bits of resolution for a large range of colors. Because the display uses OLEDs, there is no backlight, and the contrast is very high (black is really black). We picked this display for its excellent color, this is the nicest mini OLED we could find. This guide will show you how to hook it up and use it with an Arduino.

DIY 8x2 LCD Shield

Soldering an LCD to a shield

This tutorial will show you how to solder together a shield for an LCD with a 8x2 header.

Adafruit GFX Graphics Library

Show those pixels who's boss!

The Adafruit_GFX library for Arduino provides a common syntax and set of graphics functions for all of our LCD and OLED displays.

DeLorean Time Circuit

Making a functional clock inspired by the “Back to the Future” trilogy.

RGB LCD Shield

Control a 16x2 Character LCD using 2 pins

This tutorial will show you how to build and use the Adafruit RGB LCD Arduino shield. We have a great library that makes it incredibly easy to use the LCD and the 5 included buttons while only using 2 pins on the Arduino!
