Tutorial 5 for Arduino: Motors and Transistors. 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.

PCB Quadrotor (Brushless) Quadrotors are the new Segways: a mesmerizing, somewhat magical, self-stabilizing platform that every tech person wants to have.

PCB Quadrotor (Brushless)

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. Returning an Array in C. Transistor Circuits.

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.

Electric Imp promises a simpler cheaper path to the Internet of Things

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. Behind the high-tech appeal of the innovation is a rather domestic story, which is just as well since it’s in the home that it will most likely be put to work.

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. Arduino NetServer. 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.

Arduino NetServer

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. IXACP - Internet Controlled Vehicle. IXACP stands for "Internet XBee Arduino Controlled Project".

IXACP - Internet Controlled Vehicle

This project contains Arduino NetServer - Web Server for Internet Control , XBee - Wireless Remote Control the Vehicle , Arduino - Handle communication , Inputs and Outputs. Please also visit XRobot17 if you are interested in C/C++ windows programming , PC Game programming , Physics Simulation , and Computer Controlled Electronics(RC Car). Internet Controlled Vehicle uses Arduino NetServer to achieve online monitor / control. Which means the people can use an Internet Browser , such as Firefox or IE , to monitor / control their Electronic Project.

The vehicle with a robotic arm , can be controlled and monitored through an internet browser. XBee module for wireless control. The program with functions : serial port communication , Web Server , USB Gamepad operation. A tiny Web Server , one of the key functions of the program. Project – Arduino + Servo + iPhone. Projects.

Controlling an Arduino with an iPhone. Skill Level: Beginner by Pete-O | November 30, 2009 | 72 comments You can download the Source Code here.

Controlling an Arduino with an iPhone

How it works: In this tutorial you will learn how to communicate between the iPhone/iTouch app TouchOSC via a WiFi network to a Processing sketch displaying graphics and finally to control an Arduino board to light up an LED. TouchOSC is just one of many iPhone/iTouch apps that can send Open Sound Control signals. Processing is a great application for quickly creating visualizations, interactive installations, and physical computing projects. Creating the circuit: ArduinoToBreadboard. Learning Examples | Foundations | Hacking | Links This tutorial explains how to migrate from an Arduino board to a standalone microcontroller on a breadboard.


It's similar to this tutorial, but uses an Arduino board to program the ATmega on the breadboard. Unless you choose to use the minimal configuration described at the end of this tutorial, you'll need four components (besides the Arduino, ATmega328, and breadboard): a 16 MHz crystal, a 10k resistor, and two 18 to 22 picofarad (ceramic) capacitors. Circuit Symbols of Electronic Components. Introduction to C. This tutorial is designed to be a stand-alone introduction to C, even if you've never programmed before.

Introduction to C

However, because C++ is a more modern language, if you're not sure if you should learn C or C++, I recommend the C++ tutorial instead, which is also designed for people who have never programmed before. Stepper motor. Animation of a simplified stepper motor (unipolar)Frame 1: The top electromagnet (1) is turned on, attracting the nearest teeth of the gear-shaped iron rotor.

Stepper motor

With the teeth aligned to electromagnet 1, they will be slightly offset from right electromagnet (2).Frame 2: The top electromagnet (1) is turned off, and the right electromagnet (2) is energized, pulling the teeth into alignment with it.
