A tool to control and test light show controlled by the protocol DMX-512, ideal for quick tests on fixed or temporary installations of lighting. This project arises from the need to have a portable system for rapid testing in lighting installations, without the need to install lighting consoles, interfaces or computers in environments outside, hostile or difficult to access.

The purpose of this small scale LED marquee is to display messages to our classroom in a more modern and centralized way. In the classroom, this construction would save white board space and is convenient because it can store a large amount of information. It is also fairly simple to program and has a mount, making it easy to place anywhere within the classroom setting.

In this article Raj over embedded-lab.com shows us how to measure our heart rate using Arduino UNO, his Easy Pulse Plugin and 4-digit SPI seven segment LED display module. It computes the heart rate by processing the analog pulse signal output from the Easy Pulse Plugin sensor and displays it on the seven segment display module.

Hey guys, this a instructable of how to make a bike speedometer.Yeah,you read it right the one that we use in car but only for 10$ .Well the first this for you to know is that this is the collaborated project of Mr_DIY_Electrician and paurushthemaker .So back to topic our project is all about a speedometer which has 3 modes as follow:-

Piotr wrote a post on his blog about using some of advanced capabilities of ADC in Arduino Due:
Today I’m going to present some of more advanced capabilities of ADC built in ATSAM3X8E – the heart of Arduino Due.
I like the Arduino platform. It makes using complex microcontrollers much simpler and faster. Lets take for example the analog-to-digital converter. To configure it even on Atmega328 (Arduino Uno/Duemilanove) you must understand and set correct values in 4 registers. And it can be much more in complex device, like 14 in ATSAM3X8E (Arduino Due)!

In this instructable I am going to show you how to make your own printed circuit board business card. I feel that these business cards will really help you stand out from the crowd and make a great impression. It might even add one more skill to your resume. Everyone that I have given these cards out to has been really impressed and thought it was a great idea. I have regular business cards as well and I only selectively give out my circuit board cards. You can take it to the next level by soldering different circuits on the cards. I made one of my cards into a standalone Arduino.

Thinking about using Arduino to automate your home? Do it easily with our compatible board!
The Automation Board is 100% compatible with the Arduino Uno. This way it allows the enjoyment of all the easy programming and libraries that Arduino provides. It’s a strong and versatile board, with multiples resources to develop a fully automation system. The Automation Board dispenses the use of power sources.

Monitor your road speed using the Arduino. This project uses a magnetic switch (also called a reed switch) to measure the speed of one of the bike’s wheels. The Arduino calculates the mph, and send this information out to the LCD screen on the handlebars as you ride. It is compatible with any kind of bike/wheel, simply enter the radius of the wheel in the firmware to calibrate the device for your setup.

Wireless, Credit-Card sized, Android + Linux + Arduino™, Embedded Sensors, starting from $49. What else?
UDOO Neo embodies a new concept: a single board computer suitable for the Post-PC era:
- Like a Raspberry Pi, you can program it in any language and run a full Linux environment with graphic interfaces.
- You get all the simplicity of an Arduino-compatible board, thanks to the Cortex-M4 and the Arduino UNO pinout layout, with the possibility of adding most Arduino™ shields, actuators and sensors, both analog and digital.
- An incredible, smoothly-running Android 4.4.3, it gives you the possibility to build new Android-based smart devices.
- You get a wireless module: Wi-Fi 802.11 b/g/n + BT 4.0 (Classic Bluetooth and Bluetooth Low Energy), because we hate cables.
- 9-axis motion sensors are embedded, to build your perfect drone/robot/3D printers/whatever or create new kinds of interactions with the real world.
- Open-source hardware: because we love to let you hack things or create new devices from scratch!
- Starting from $49!
