One of the most interesting shield that you can mount on the Arduino platform is certainly the ethernet shield, because enable numerous networking applications such as remote control of systems and users, web access and publication of data, and more yet, the simplicity of finding and integrating open-source libraries on Arduino IDE does the rest. The usefulness of LAN connectivity has meant that the market would respond by offering different ethernet shield, first of all the original Arduino Ethernet Shield, which was accompanied by the good shield by Seeed Studio, both of these circuits are based on the chipset WIZnet W5100, allow multiple socket connections and can work at 100 Mbps

The Arduino team is now shipping their latest creation – the Leonardo. It is the first Arduino to use Atmelʼs ATmegaXU4 series chip with built-in USB. This change is big and it has big benefits. In addition to the built-in USB, it offers more digital and analog pins. This comprehensive guide gives you the details you need to know to start using it – pinout differences, hardware capabilities, new software libraries and more.

The Simplecortex is a microcontroller dev board with an ARM Cortex M3 from NXP.
The Simplecortex is a microcontroller development board that is shield compatible with the Arduino. The Simplecortex has a fast microcontroller, the LPC1769 from NXP. This is a ARM Cortex M3 microcontroller with 512KB flash, 64KB RAM and it runs at 120Mhz. To make sure that the Simplecortex is easy to use we made tutorials for almost every peripheral on the chip and examples to get you started. There are tutorials for simple stuff like IO control up to more advanced tutorials for MicroSD cards. If you have ideas for a new tutorial or made a tutorial yourself, feel free to drop an email or post it in the forum. The Simplecortex also has an onboard debugger. It can also be used to program external devices like a self made PCB for your own project. No more microcontrollers with pre-programmed bootloader needed.

IRVINE, CA — June 19, 2012 — Open Source RF, a new venture dedicated to serving Arduino users by making high-quality, creative products for the Maker, DIY and Open Source communities, today announced it is releasing a plug and play wireless Shield for Arduino.
The Wireless Inventors Shield makes any Arduino project wireless instantly even in high-traffic areas. Using a reliable wireless RF module, the Shield allows users to easily send and receive error-free data between two or more Arduino boards.
Arduino is an open source electronics prototyping platform based on flexible, easy-to-use hardware and software. It is intended for artists, designers, hobbyists and anyone interested in creating interactive objects or environments.
The Wireless Inventors Shield has been tested at ranges in excess of 500 feet (150 meters); it is plug and play and error free, featuring built-in forward error correction and data recovery so users receive only cleaned and cyclic redundancy checked (CRC) verified data; and it is simple to use in that inputted data is wirelessly transmitted then cleanly received on the opposite end.

Everybody are making Arduino clones. So I thought I should make THE smallest. I took smallest package atmega88 – 28qfn (5mm x 5mm). Routed smallest possible resonator and as much pads as i could fit on in.
The result – Smallest Arduino clone ever! Size is only 7.4mm x 7.4mm! Features include:
- Auto reset
- 4 analog channels
- 1 digital i/o
- one LED
- funny readme with BOM
It needs arduino bootloader for atmega88 like ottantotto bootloader, probably it needs some hacking too because the resonator is 8MHz not the Arduino regular 16MHz.

If you spend any time playing with Arduinos, ATtinys or looking at AVR spec sheets, you soon encounter a bewildering smörgåsbord of acronyms for various communication protocols. With examples such as I2C, LIN, SPI, TWI, USI, etc., it can get pretty confusing. What do these terms mean? How do you choose the chip that meets your needs? How do you make use of these protocols? This guide will take the mystery out of all these acronyms, and provide a brief overview of what they mean and how you use them in your projects.

It’s my first post in English on this blog, just to get to the broader English crowd of the maker world. I’ll present my latest project, the fifth iteration in my quest to create a remote control for my DSLR.
There’s a night-mode, where all the LCD turns red, useful for astro-photography, when you need to be able to look at it without compromising your acquired night vision. The interface is limited to a single rotary knob you can push to validate your choices. It remains easy and intuitive to use even when it’s minus 20°C and it’s pitch black. The output is a standard 3.5mm stereo jack, you can use different cables to control different brand of DSLRs.

I am using a Netdunio-Plus board (Physically looks like Arduino but is using C# as programming language) to display current and forecast weather information. I pull the information from Weather Underground. I recently posted a similar project where an Arduino board was used to show forecast of the weather from Google Weather service. This project is fully automatic, no configuration required, and there several enhancements to the graphical display (and bug fixes).
