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.

RGB & HSV NeoPixel Dialer

Dial in the perfect color for your NeoPixel projects

Using a Feather M0 Express running CircuitPython, the NeoPixel strip's RGB values are affected by 3 potentiometers and displayed on an LCD.

Mystery Box: NeoMatrix Mk I

Metro Minimalist Clock

What time is it? Metro Mini time! Build this stylish, minimalist clock.

It's a clock. Made of love. And a Metro mini, a realtime clock module, and a 7-segment display backpack.

Mindfulness Clock OF DOOM

A grim reminder that time is priceless

by Phillip Burgess

It’s not pleasant thinking about one’s mortality, but that’s the point of this project: to make one aware of the passage of time and how precious each minute is. As you look at the clock, remember that you are never getting those minutes back. Stop watching internet cat videos and make the most of them!

14-Segment Alpha-numeric LED FeatherWing

so many segments

This is the Adafruit 0.56" 4-Digit 14-Segment Display w/ FeatherWing Combo Pack! Display, elegantly, 012345678 or 9! Gaze, hypnotized, at ABCDEFGHIJKLM - well it can display the whole alphabet. You get the point. It is a nice, bright alphanumeric display that shows letters and numbers in a beautiful hue.

7 Segment Display Internet Clock

NTP-enabled clock in your favorite color

by Philip Moyer

Get the ultimate in time precision with an Internet-synced clock. A Feather M0 WiFi + seven segment display FeatherWing, configured to use NTP to set and display the current time.

Adafruit 7-Segment LED FeatherWings

Give your Feather some big numbers

7-Segment Matrices like these are 'multiplexed' - so to control all the seven-segment LEDs you need 14 pins. That's a lot of pins! Here at Adafruit we feel your pain. After all, wouldn't it be awesome if you could control a matrix without tons of wiring? That's where these 7-Segment LED FeatherWings come in!

Raspberry Pi Physical Dashboard

Build a dashboard to visualize data on LED displays and automotive gauges!

Use a Raspberry Pi and Adafruit Motor HAT to control LED backpack displays and automotive stepper motor gauges built into a reusable dashboard. Great for monitoring anything you can imagine!

Adafruit FT232H With SPI & I2C Devices

Use the Adafruit FT232H USB to GPIO / SPI / I2C breakout with Adafruit's SPI & I2C devices.

Learn how to use Adafruit SPI & I2C devices that support the Raspberry Pi & BeagleBone Black with the Adafruit FT232H breakout and your PC!

Character LCD with Raspberry Pi or BeagleBone Black

Use a 16x2 or 20x4 character LCD with a small Linux board!

How to wire up and use a 16x2 or 20x4 character LCD with a Python library for the Raspberry Pi or BeagleBone Black.

PiMiner Raspberry Pi Bitcoin Miner

Use a Raspberry Pi to control & monitor your USB bitcoin miners

by C. Cunningham

This tutorial will show you how to install bitcoin mining software on your Raspberry Pi and use a 16x2 Character LCD Plate to monitor your crypto-currency creation.

Character LCD System Monitor

Mini display, maxi information.

by Phillip Burgess

How to use our LCD + USB/Serial backpack (with stand) as a realtime system status monitor. Great for “headless” systems!

Large Pi-based Thermometer and Clock

Build a large LED Thermometer / Clock using a Raspberry Pi

This project combines a whole heap of modules to enable a Raspberry Pi to power a large 1.2 inch 4 digit 7 segment display. A small switch switches the display between showing the temperature and the current time. The project uses a real-time clock (RTC) to ensure that the Pi always has the correct time, even if it is not connected to the Internet.

USB + Serial RGB Backlight Character LCD Backpack

Control an RGB Character LCD with USB or TTL Serial

by Tyler Cooper

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.

Reverse Geocache Box

For proposals, or for fun!

by Tyler Cooper

Adafruit customer Kenton Harris shares how he proposed to his girlfriend using a reverse geocache box. Learn how a reverse geocache box works, and how you can build one for yourself.

Adafruit 16x2 Character LCD + Keypad for Raspberry Pi

This new Adafruit Pi Plate makes it easy to use an 16x2 Character LCD with a Keypad

This new Adafruit Pi Plate makes it easy to use an RGB 16x2 Character LCD. We really like the RGB Character LCDs we stock in the shop. Unfortunately, these LCDs do require quite a few digital pins, 6 to control the LCD and then another 3 to control the RGB backlight for a total of 9 pins. With this in mind, we wanted to make it easier for people to get these LCD into their projects so we devised a Pi plate that lets you control a 16x2 Character LCD, up to 3 backlight pins AND 5 keypad pins using only the two I2C pins on the R-Pi!

Drive a 16x2 LCD with the Raspberry Pi

Output Character Data to a Inexpensive Display

by Michael Sklar

Adding a LCD to any project immediately kicks it up a notch. This tutorial explains how to connect a inexpensive HDD44780 compatible LCD to the raspberry pi using 6 GPIOs. While there are other ways to connect using I2C or the UART this is the most direct method that get right down the bare metal. This technique allows for less expensive LCDs to be used, it does not require any i2c drivers and it won't steal the only serial port on the Pi.

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!
