Very minimal Arduino-compatible circuit

I saw some days ago a pointer to The ultimate low-cost dev board. Or at least looks pretty close to it. The shrimp is a very, very minimal Arduino-compatible circuit meant to control all the pins on an ATMega328. The components only cost about £1.40 ($2.25 USD) when bought in volume, making it perfect for


OpenPLC, for industrial automation to Halloween displays article factories have programmable logic controllers to take care of their automation tasks and they are also good devices to control your Halloween effects. open-plc project is an open hardware design to build your own programmable logic controller. Included in the OpenPLC are four 24V inputs, four 24V

PCBs without any substrate

PCBs without any substrate article tells that Kimio Kosaka is taking the concept of free-formed circuits to the next level with O’Baka Project No.7. Arduino Skeleton “0′baka Project” means a stupid project. This project is to make things which is not art and which is not usable. It’s a fully functioning Arduino board, without the

Arduino and Raspberry Pi together

Raspberry Pi and Arduino seems to be the most interesting small single board platforms at the moment for the hobbyists. It is a bit sad to see some people who are very passionate about the Arduino community coming down quite hard on the Raspberry Pi project as the Big Bad, suggesting that we’re trying to

Arduino Ethernet Shields

The Arduino Ethernet Shield connects your Arduino to the internet. Just plug Arduino Ethernet Shield module onto your Arduino board, connect it to your network with an RJ45 cable and follow a few simple instructions to start controlling your world through the internet. The original Arduino Ethernet Shield is based on the Wiznet W5100 ethernet

Arduino Motion-Sensing SMS Alarm Project

Surprisingly Simple Arduino Motion-Sensing Project Makes For Some Weekend Fun article tells that Matt Williamson built a tiny, Arduino-based motion sensor that will SMS you when something moves by your desk or into a room. It’s completely open source and the notifications system runs on your PC thanks to a simple Python script. Why is

Shrinkify Your Arduino Projects

If you have a simple Arduino project that uses only a few pins, you might be able to shrink it down to a single 8-pin ATtiny chip. How-To: Shrinkify Your Arduino Projects video and How-To: Shrinkify Your Arduino Projects article shows you how. The best part is you can use the same Arduino code and


Fritzing is an interesting open-source initiative to support designers, artists, researchers and hobbyists to work creatively with interactive electronics. We are creating a software and website in the spirit of Processing and Arduino, developing a tool that allows users to document their prototypes, share them with others, teach electronics in a classroom, and to create
