This project by Ed Zarick is an Arduino based vehicular control system known as JEEPuter. It combines 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.

This project is about interfacing a SNES controller and 16×2 LCD to a PIC16f84A to type out which buttons are pressed.

A while ago, I bought a LCD117 serial LCD backpack from Modern Device to save a few pins on my Arduino board. Everything worked great because the micro-controller, the serial backpack and the LCD display all required 5 volts for power and logic levels.
But when I tried connecting the serial LCD backpack to a netduino micro-controller, nothing worked: the netduino uses 3.3 volt logic levels while the LCD117 serial backpack expects 5 volt logic levels.

This article discuss 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. If you are looking to drive a LCD via parallel interface and Arduino then take a look at LiquidCrystal library. [via]

This project interfaces a ProGin SR-87 GPS module with an ATtiny2313 and a 2×16 LCD to generate a running lat/long display. The device can also store a location and trigger a buzzer each time that location is reached. Source code and schematic are provided. [via]

The idea was to make a Reverse GeoCaching box with custom hardware and cheap parts. As we already know, Reverse GeoCaching is relatively new thing where the idea is that you already have the “treasure” in your hands, but in order to access it you must go to a specific location. Once you get there, the box opens and the treasure is yours. The box doesn’t show you the destination coordinates but only the distance and also a limited number of clues and that’s where the fun starts.
This Reverse GeoCaching box’s hardware consists roughly of: ATmega328P microcontroller, graphic display from Nokia 3310 phone with backlight, Li-Ion BL-5C battery from Nokia phone, MAX1811 Li-Ion charger IC, PC USB GPS receiver, Mini Servo and other bits and pieces.

Simon Inns builds this realtime PIC based audio spectrum analyzer. The analyzer uses Fast Fourier Transform routine written in C to run as efficient as possible on the 8 bit PIC18F4550 mcu. The output from the FFT is displayed using a 128×64 graphical LCD to allow a real-time view of an audio signal. [via]

This mini-tutorial will go through the process of setting up a ST7565 LCD. These LCDs are graphical which means they can display pixels, not just text. This type of LCD in particular has 128×64 pixels, which appear dark gray on a green-blue background. They have a backliight but can also be used without the light on for daytime visibility.

This project is a high quality PLL FM transmitter with output power of 5 W. The transmitter includes RDS/SCA input and Audio/MPX input with optional pre-emphasis. It can be used with or without stereo encoder. Tuning over the FM band is provided by two buttons that control dual-speed PLL. The transmitter can work also without the LCD display.

Saeki Yoshiyasu build a remote controlled GLCD using an Arduino and iPod touch. The project uses a Graphics LCD (KS0107) and for controlling GLCD, he used Arduino and KS0108 library. Firstly he wrote the Arduino code that Arduino receives a drawing data from serial port and draws a picture on GLCD. Secondly he wrote the WebSocket Server in Python/Tornado. This server receives a drawing data from iPod touch/Safari through WebSocket connection and sends the data to Arduino thought Serial port. He used pySerial for Serial communication. Finally he wrote a web page for drawing a picture and sending a drawing data. [via]
