What Arduino can do Arduino can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators. The microcontroller on the board is programmed using the Arduino programming language (based on Wiring) and the Arduino development environment (based on Processing). Arduino projects can be stand-alone or they can communicate with software running on a computer (e.g. Flash, Processing, MaxMSP). The boards can be built by hand or purchased preassembled; the software can be downloaded for free.

Intro / Home Page
So, I get two or three emails a day, all basically asking the same thing: "Where can I learn about electronics?" In general, most of these people have seen some of my projects and want to be able to build similar things. Unfortunately, I have never been able to point them to a good site that really takes the reader through a solid introduction to microcontrollers and basic electronics. I designed this tutorial course to accompany the Arduino starter pack sold at the Adafruit webshop. The pack contains all the components you need (minus any tools) for the lessons Arduino Tutorial - Learn electronics and microcontrollers using Arduino!

Arduino Tutorials

Arduino Tutorials This is the start page for our series of over fifty Arduino tutorials. Each tutorial from chapter zero to thirteen will cover a variety of topics and lessons, then from chapter fourteen each chapter will cover a particular topic. If you are looking to learn about the world of Arduino – this is a great place for beginners to start, or for more experienced users to brush up on their knowledge. Scroll down to read the contents of each chapter. New tutorials, lessons and other articles of interest are announced via twitter, Google+, RSS feed and by email – to keep up, subscribe using the form in the column to the right.

4 Operating Systems for the Arduino I was working in the lab, late one night, when my eyes behold an eerie sight... Yes, Halloween is a long time ago, but that stupid song is still stuck in my head. I miss Halloween. I never got to post up pictures of my skeleton running off IXM's. :-)Anyway, I was browsing the Arduino forums and saw this cool post about DuinOS, a real-time embedded "operating system" for the Arduino. DuinOS by RobotGroupIt's a simple little realtime OS (RTOS) built by the guys at RobotGroup (hello!), and can be downloaded here.

www.electricstuff.co.uk Each of the three main sections has a 'tour' facility for easier navigation through the pages - clicking on the small icons at the corners of each page will move to the next or previous page in that section. Upcoming public demos, events etc. I'll be participating in None at present. I can often be found lurking or presenting at Dorkbotlondon meetings.

Transformers

Transformers

In the photograph, note that the coil on the left has fewer coils than that at right (the insets show close-ups). The sketch and circuit show a step-up transformer. To make a step-down transformer, one only has to put the source on the right and the load on the left. (Important safety note: for a real transformer, you could only 'plug it in backwards' only after verifying that the voltage rating were appropriate.)

Handbook of hardware pinouts, cables schemes and connectors layouts

We are gathering and investigating information about interfaces of modern and obsolete electronic hardware including pinouts of interface ports, expansion slots, other connectors of computers and other electronic devices. Information about functions of pins in connector (pinout) is essential for everyone who wants to investigate modern computer hardware, explore the way it's works, connect various devices to computer, produce DIY electronic devices. Our handbook features 1629 documents with: Pinouts of computer hardware components, internal connectors, buses and input/output ports (i.e. PC Serial port pinout, PCI Bus ).

Build the BASIC SPY TRANSMITTER - Page 1 of 16

Build the 2 transistor Spy Transmitter Radio frequency projects can seem more difficult than most electronics projects because most of the time you cannot build them on a solderless breadboard and there may be parts used that are not easy to source such as coils and adjustable capacitors. This project is focused towards those who have not yet attempted to build any kind of RF project, and it is laid out in such a way as to make it easy to explore the basic principles of RF circuitry and ensure a successful final product. This simple 2 transistor audio transmitter will send the sounds picked up in a room to any FM radio tuned to the same frequency as the transmitter, somewhere between 80 and 100 Megahertz. The expected range will be at least 100 feet and could be substantially longer depending on the parts used and the quality of your final product.
