Forums - The Front Page The AeroQuad is an open source hardware and software project dedicated to the construction of remote controlled four-rotor helicopters, also known as quadcopters or quadrocopters. The latest software also support additional multicopter configurations! Buy AeroQuad Parts HereDownload the AeroQuad Software AeroQuad hardware typically consists of the fully-featured STM32-based AeroQuad32 flight controller board or an Arduino microcontroller (Mega 2560 or Uno) as the flight controller board, and an AeroQuad shield with various sensors, such as an accelerometer, gyroscope, magnetometer (heading), barometer (altitude hold) ultrasonic sensors and GPS. Below you'll find an overview of the features AeroQuad offers you: Multiple flight configurations are supported: Development: For information on the development of AeroQuad, see the AeroQuad GitHub Repository, the AeroQuad Developers Guide and our Wiki.

Pulsar Kites Pulsar kite video It is fun to play with kites in Helsinki since there is a good wind current during most part of the year. The interface has a wireless system that measure the speed and rotation of the kite, thus this data is transformed into sound on real time.

Arduino Parts & Kits Online Melbourne, Buy Microcontroller Boards, Arduino Electronic Components - Welcome How to Connect Multiple Arduino Microcontrollers with I2C Use I2c to connect several Arduinos together to combine their power. I2C stands for the Inter Integrated Circuits and is one of the best Multi Master Serial Computer Bus technologies used in different systems to connect the peripherals of low speed data transmission. The technology was invented by Philips for TVs but is used in all sorts of applications including our Wiimote and Arduino tutorial. The I2C circuits follow a standard operational procedure where only two bi-directional lines, a serial clock, and a serial data systems are used.  There are recently improved versions of I2Cs available on the market which can hold a higher number of nodes and can perform faster than the rest. Don’t miss: Top 40 Arduino Projects of the Web You can use I2C then you will be able to connect more than one Arduino to a robot or other application and you can easily establish a network of sensors. How To Set Up Your I2C

Arduino Stand Alone The following outlines how to build a stand alone Arduino on a bread board. This tutorial is based on the original explanation at the Arduino site. I have not included a schematic here -- if you follow the one at the Arduino site note the listed errors -- they are corrected in the info below. Note: I am using a resonator with built in caps -- not a crystal. The crystal breadboards more cleanly -- but the oscillator reduces part count (sort of). Parts List ATMEGA168 chip (blank) 16M crystal reset button 10K resistor jumper wires Getting Started Let's first look at the full system that we will be making so that you can plan your breadboard. On a MAC this serial strategy requires a serial to USB converter -- i.e. a KEYSPAN adaptor. Connections Start with your bootloaded Atmega168 on the board. First connect power to the chip. Finish power connections by jumpering pin 20 to 5V. Another view. The 10K (brown-black-orange) resistor is needed even if you don't have a switch. Completed Circuit

My Arduino Secret-Knock Gumball Machine One of the best things about exhibiting at Maker Faire is giving attendees a challenge. For the 2010 Maker Faire Bay Area, I decided to combine a past project of mine, a door lock that opens only when you give a secret knock, with a standard crowd pleaser: candy. The result was this Secret-Knock Gumball Machine, which tempted and tested the crowds at Maker Faire to guess the right rhythm and receive a treat. Since the knock was not terribly secret (I happily handed out hints), it distributed hundreds of gumballs over the event’s two days. The “secret” knock defaults to the famous “Shave and a Haircut” rhythm, but you can program custom knocks by simply pressing a button and knocking a new pattern. The machine only listens for the rhythm, not the tempo, so the correct knock will dispense a treat whether you perform it fast or slow. Downloadable files MAKE: Amends

Introduction to I2C In this article Grinan Barrett introduces us to I2C. Grinan explains how I2C works, provides many useful links to information related to I2C and example Arduino code for a robot project where multiple Arduino boards are used for sensing and control. Grinan submitted this article to uCHobby as part of the uCHobby Giveaway program. What is I2C? I²C uses only two bidirectional open-drain lines, Serial Data (SDA) and Serial Clock (SCL), pulled up with resistors. The I²C reference design has a 7-bit address space with 16 reserved addresses, so a maximum of 112 nodes can communicate on the same bus. The maximum number of nodes is limited by the address space, and also by the total bus capacitance of 400 pF, which restricts practical communication distances to a few meters. Wikipedia Definition What exactly does the I2C protocol and usage mean to the average robot builder? A simple I2C network setup Setting up and using i2c · Two or more Arduino · The latest Arduino IDE · 2 – 1.5k pull up resistors

Home Tech: Drawing an Arduino Circuit Diagram I've had an Arduino Duemilanove now for a couple of weeks. If you're not familiar with the Arduino, it is "an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software". It has a small microcontroller, a USB port to connect to your computer for programming, a power socket for providing power when the USB cable isn't connected, and various digital and analog input and output pins, for connecting up to leds, switches and various sensors. It's inexpensive, and there's an open source IDE for programming. So I went looking for a program that would let me document my circuits, and I found Fritzing. Here's an example of a circuit using the Arduino Duemilanove and a 7 Segment Red LED 0.3" Digital Display (RadioShack 276-075). Building this I was able to experiment with another feature of Fritzing, because the 7 Segment LED included in the core parts of the tool was a common anode numerical display.
