I just happened to see some large strips of LED lighting when I was picking up some parts at Maplin which were on sale (if I remember correct they were around £12 per approx. 2m strip) however the controller/driver was still around £40, so I thought I would just build a better one myself.
I wanted it to be a web enabled controller as there are a lot of cool things that can be done with a device once it is accessible over HTTP, and I am working on a home automation server project so it would be good to have some devices which I can test this with.

This Instructable will demonstrate the building of a bare bones (and really inexpensive… less than $5) Arduino compatible module that can be put together on a small piece of stripboard and can be used either on a breadboard or independently.

Arduino quadcopter iPhone control:
This Arduino Quadcopter by Kyle Fieldus has iPhone Control, similar to the AR Drone you can tilt the phone to control the quadcopter. Touch OSC is being used to design the phone interface, there is also an Android version available. The system chain is a bit complex since the phone is sending the input data to the computer, the computer determines what should be done on the quadcopter and sends these commands to a computer tethered Arduino via USB. The computer tethered Arduino finally sends the commands to the quadcopter mounted Arduino via Xbee. All of the code and instructions will be made available as soon as this University project has been handed in and graded. You can see the first video here that was taken when the Xbee link between the two Arduinos was tested.

The Arduino library has always had an “analogWrite()” function, even though the ATmega doesn’t have any way to generate a varying voltage. So why the name?
Well, what most microcontrollers can do is generate a pulse-width modulated signal, also known as PWM. That’s just a fancy way of saying that the microcontroller periodically generates a pulse, of which the width can be varied under software control.

Seeedstudio has announced what may be the smallest Arduino compatible board yet. The BareDuino Nano was designed by 15 year old maker Niek Blankers from the Netherlands, and sports the same processing power as Arduino Uno in a 21×14 mm footprint and includes an FTDI programming interface and on-board voltage regulator.

TechBitar wrote this Instructable detailing his ANDRUINO, the 2-way Android controller for Arduino via bluetooth:
ANDRUINO is a simple tool to help you control your Arduino (or clone) from your Android phone. It’s both an Android app and an Arduino program. Andruino has a simple Android user interface to 1) control Arduino’s digital and PWM pins 2) send text commands to Arduino 3) and receive data from Arduino over Bluetooth using the ever popular HC-05 Bluetooth over serial module or its siblings.
Andruino should work with other Bluetooth modules with some tweaking but I have only tested it with the HC-05. This is an alpha version that’s running fine on my Samsung Galaxy S2 Plus. Please share your experience running Andruino on your phone.

A light meter is a device that measures the intensity of light. It finds applications in schools, hospitals, production areas, passageways and more to measure and maintain proper lighting levels. It is often used by photographers to determine the proper exposure for a photograph. Today we are going to build a simple light meter using an Arduino board and a BH1750 digital light sensor. The measured lighting level or intensity is displayed on eight seven segment LED displays, in both Lux and Foot-candle units.

Ihsan informs us of Digitstump’s inexpensive, powerful Arduino-compatible board with WiFi – the DigiX:
Have you seen this DigiX board by Digistump? They are the ones who created the Digisparks as well. As a difference from Digispark, this time they are aiming high end region of the devboards.

Do you think programming is difficult? Did you think Robotics is just for programmers?
We don´t think so. Our aim is to make robotics accessible to everyone.At Minirobots we have developed mOwayduino, an open source robot, based on Arduino technology. mOwayduino robot is ready to program, with multiple built-in sensors, motors and more.You don´t need to have any robotics background to start working with mOwayduino.
