Atmel STK500as an Arduino dev board

How to configure an Atmel STK500 as an Arduino-based development system.

AVR Flash Loader

This project uses a WIZnet WIZ810MJ board to connect an Atmel Butterfly development board to a PC host application via ethernet.

USB 8bit Interface Board

An USB interface board which can be used to connect 8 data lines to the USB. The interface comes with a small internal FIFO (384 byte Tx, 128 bytes Rx) and 4 handshake lines which make it suitable for interfacing microcontroller designs to the USB.

USB game controller with 12 inputs

For some projects, a circuit making it possible to connect 12 buttons (including 4 directional buttons) to a PC using an USB port is very useful.

Nokia F-Bus

Most Nokia phones have F-Bus and M-Bus connections that can be used to connect a phone to a PC or a microcontroller. The connection can be used for controlling just about all functions of the phone, as well as uploading new firmware etc. This bus will allow us to send and receive SMS messages.

A short announcement: I've prepared the RSS feed for the PicList.com mailing list. You can find it here: https://feeds.feedburner.com/pic-list. Enjoy.

Sakura - The World’s Simplest Open Source DIY MP3 player!

For around $30 in parts and a good amount of patience, you can have a completely open source and hackable mp3 player ready to go. It can be modified to accept serial commands, be embedded in an art project, used as the voice of your next smart talking robo-sidekick, or filled with music and used as is. Put in whatever size card you want, up to the theoretical limit of the MMC format.

Stereo PWM audio

Using a pwm channel of a simple microcontroller, a capacitor and a resistor to reproducting sounds.

SPI2CF - WLAN solution

The complete WLAN solution for AVR and other CPUs.

Scopey II
