Tutorial 5 for Arduino: Motors and Transistors | JeremyBlum.com This tutorial was featured on the official Arduino blog on 3/9/2011 This week, we’ll finally be using the Arduino to control some motors! First up, we’ll control a standard DC motor running off a 9V battery with the help of an NPN transistor and a PWM (Pulse Width Modulated) signal from the Arduino. Next, it’s onto 180 degree servo motors, which we will power on an independent 5V rail using a voltage regulator.
Quadrotors are the new Segways: a mesmerizing, somewhat magical, self-stabilizing platform that every tech person wants to have. You can't ride a quadrotor (well, maybe you can), but they do fly, and you can build one yourself from scratch! I helped with a previous quadrotor build (Instructable here), and after flying it I decided I wanted to make my own. I had an idea to make a miniature one comprising a single printed circuit board that is both its structural frame and its electronics motherboard. The end result was "4pcb", a 138-gram micro quadrotor. I designed it in EAGLE, soldered it, and tested it over the course of a few months. PCB Quadrotor (Brushless)

Warning!!! This project deals with AC electricity which is dangerous if you don’t know how to treat it safely. You must treat electricity with caution. There are many books and websites about electrical safety procedures and if you’re not sure how to be safe you should read that information. The most basic advice I can give is always assume any exposed wires are live and touching them will hurt a lot at best and kill at worst.

Los Altos-based start-up Electric Imp is looking to make putting the "things" into the Internet of Things both cheaper and simpler with Imp - a Wi-Fi equipped card designed to connect appliances to the internet so that users can remotely monitor and control them. A similar concept to the Twine system we saw back in 2011, Imp is geared towards simple installation and works with a range of appliances. The biggest novelty here is that the card combines the power of Wi-Fi with cloud computing provided by Electric Imp, so manufacturers don’t need to create specific management software. Users can link up with other users and services online as well as monitoring the device connected with the Imp through a web-browser or smartphone. Electric Imp promises a simpler cheaper path to the Internet of Things
What are microcontrollers? They are what their name suggests. Today they can be found in almost any complex electronic device - from portable music devices to washing machines to your car. They are programmable, cheap, small, can handle abuse, require almost zero power, and there are so many variaties to suit every need. This is what makes them so useful for robotics - they are like tiny affordable computers that you can put right onto your robot. How to Build a Robot Tutorial - Society of Robots
To achieve Internet Controlled Electronics , in the other words , the main functions of Arduino NetServer are : Web Server handles the communication between your PC and Internet User. Serial Port will be the interface between your Arduino (electronics) Project and PC. This is how you control / monitor electronics from internet. With this simple homemade Web Server function , the user does not need to install any other heavy software for Web Server. The tutorial of how to make your own Web Server can be found here.

Simple Bots What is a bot? Is it an abbreviation for robot? Perhaps. You could say that. I, on the other hand, like to think of a bot as an abbreviated robot.
[Javier] must have an awesome academic adviser. For his master’s thesis, he turned a building into a Rubik’s cube. Somewhere on the campus of the University for Artistic and Industrial Design in Linz, Austria, there’s a building with a whole bunch of colored, programmable lights on the facade. [Javier] thought this would make for an excellent Rubik’s cube, and set to work convincing his thesis advisers this idea was possible, and building the hardware and software. Since only two sides of the building are visible at any one time, [Javier] needed to build a controller for this project. The solution was to build a normal Rubik’s cube and stuff a microcontroller and a FreeIMU in the center. arduino, electronics, robotics, hacking) - #42
