Arduino

Polyphemus

An interesting idea: Revitalize a Butterfly kit with well-known lowcost Nokia 6100 color display.

I2C example with the DS1307 RTC

An example of connecting I2C device to AVR - how to connect DS1307 RTC module with an Arduino?

Glade - AVR audio library

Glade is a simple, easy-to-use, 8-bit audio library for the Arduino. It allows you to play sound on the pin 11 of the Arduino board using PWM.

Interfacing an optical mouse to the Arduino

About connect the optical sensor from a cheap mouse to your Arduino and have it read out the x- and y-movements.

Cheap color LCD with Arduino

A Nokia 6100 (or 6610) LCD display driver for use with the Arduino micrcontroller platform.

Sanguino

A bit more powerful than Arduino, but compatible with Arduino: Sanguino.

MIDI for microcontrollers

MIDI, or Musical Instrument Digital Interface, is a specification for a communications protocol between digital synthesizers and other digital music devices. It was developed to be as simple and general as possible, to give synthesizer manufacturers as much flexibility as possible, yet still have their instruments talk to each other without communication problems. Here is a simple circuit for MIDI output that works well with Wiring or Arduino, the PIC microcontrollers, the BS-2, and the BASIC ATOM Pro24.

AVR and 1-Wire interface

Dallas Semiconductor (Maxim) produces a family of devices that are controlled through a proprietary 1-wire interface. On a 1-wire network, a single "master" device communicates with one or more 1-wire "slave" devices over a single data line, which can also be used to provide power to the slave devices. How to connect such devices to Arduino?

Arduino Nano

Arduino Nano is a surface mount breadboard embedded version with integrated USB. It is a smallest, complete, and breadboard friendly. The Nano was designed and is being produced by Gravitech.

DS brut

DS brut is an open source hardware prototyping platform for the Nintendo DS
