What do you do if you have a spare LCD module with backlight, a weird 16 button keyboard, and a PIC16F877A microcontrering dust? If you’re avtanski, a monster Martian Clock immediately springs to mind. This thoroughly documented project shows you how to take these few common components and build a unique clock that features 16 […]

Arduino and TFT LCD tutorial
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. […]
Atmega644 rock paper scissors game
Students Ling-Wei Lee and Kevin Tang at Cornell University developed a version of the rock paper scissors game using an Atmega644, CMOS camera module and a 2×16 LCD. Their project requires the human player to wear a glove that has black tape on each finger. Upon a signal from the LCD, the player plays their […]
Arduino + Jeep = JEEPuter
Ed Zarick has released details on his Arduino vehicular control system known as JEEPuter. Combining an Arduino UNO, shift registers, LCD display, pushbuttons and a relay board, Ed interfaced this controller to his Wrangler’s ignition, garage door opener, lighting systems (with light-sensitivity control), radios and more. The JEEPuter also includes a time and temperature display. […]
Updated Bus Pirate LCD adapter
The previous and current batch of the Bus Pirate LCD adapter have some minor updates: Clearer labeling is a lot easier to read The backlight section has a footprint (no parts yet) for a dimming circuit using the PWM on the Bus Pirate AUX pin. This isn’t tested yet, so we didn’t populate the parts, but […]
Arduino talking to an I2C LCD display
StrangeParty demos how to use the Matrix Orbital 20×4 display with Arduino via I2C using the Wire library. The LK204-25 is a serial display, so connection to the Arduino requires just two wires to accept I2C commands and data. We expect this same procedure would work with other manufacturers’ I2C LCDs. Simple and useful if […]
Bus Pirate LCD adapter back in stock
The Bus Pirate LCD adapter v2 is back in stock at Seeed Studio. Get an LCD adapter for $9.
Simple GPS display using Attiny2313
In his project, Binu from avrprojects.info interfaces a ProGin SR-87 GPS module with an ATtiny2313 and 2×16 LCD to generate a running lat/long display. The device also will store one static location, and produce an audible alert each time that location is reached. (More locations could be provided for in code, but the project assumes […]
Reading and writing Atmega168 EEPROM
Here’s a tutorial from Protostack for beginners on how to read and write EEPROM on the Atmega 168 and display the values on an attached LCD. Includes source code in C.
Adafruit 128×64 Graphic LCD
Clearing out old posts before the new year, some of these might seem ancient. We like this graphic LCD from Adafruit. The ST7565 has a resolution 128×64 pixels, and runs at 3.3volts. Adafruit will even includes a level translator so you can use it with 5volt microcontrollers.
Launchpad plus LCD equals serial terminal
The Philadelphia, PA based Maker/hacker group Hive76 developed a tiny serial terminal using a TI Launchpad and an HD44780 LCD. The circuit diagram and code libraries are available for download. Some useful work that can be incorporated into larger projects.
NEW PROTOTYPE: USB Universal LCD backpack
The USB Universal LCD backpack controls LCDs with up to 16 interface pins at 3.3volts or 5.0volts. This includes common HD44780 character LCDs and larger graphical LCDs. Small backpack mounts behind most LCDs USB control for common 1×8, 1×16, 2×8, 2×16 … up to 4×40 character displays and some graphic displays 3v3 and 5v LCDs […]
Reverse engineering an LCD
rossum guides us through reverse engineering several LCD displays. Via Hack a Day.
I2C / SPI character LCD backpack
Adafruit has a clever new I2C/SPI LCD backpack based on an MCP23008 IO expander and a 74HC595 IO expander.
PIC LCD backpack with LCD Smartie
This is a prototype of the open source PIC LCD backpack driven by LCD Smartie over a USB virtual serial port. Follow our progress in the development thread.
DIY offline Wikipedia reader
This DIY Wikipedia reader uses a touchscreen for display and navigation. Articles are stored on SD cards in a compressed format. This version is based on the LPC1114 ARM Cortex M0 microcontroller, but there’s earlier prototypes based on AVRs. Video after the break. Via the forum. Thanks Markus!
USB LCD backpack display trials
Testing the USB LCD backpacks with two different character LCDs. We’ve noticed ghosting in several different brands of blue/white LCDs, have you had a similar experience? Follow our progress in the development thread.
More USB LCD backpack testing
IPenguin tested the full and mini USB LCD backpack. Follow our progress on this project in the forum.
USB LCD backpack testing
The full and mini version of the FT232 USB LCD backpack worked right away. Follow our progress in the development thread. We’ve requested a quote for this project, an initial batch will be available about three weeks after we send the final manufacturing package.
Comments: Seeed Studio’s outstanding service
Seeed Studio goes above and beyond to make our projects a success. Thanks guys! The two LCD adapters v2 I received from Seeed about 2 weeks ago were missing the the cables, too. I never reported this to Seeed. To my surprise a little box with 2 connector cables from Seeed was in my mail […]
