Question: What do a light-up neck warmer, an RC lawnmower, a silly-string shooter and an automatic coffee roaster have in common?
Answer: They’re all DIY projects based on the open-source Arduino controller.
If you’re an artist, designer, or creative-minded DIY type, then Arduino should definitely be on your shopping-list. Arduino is, in essence, a small piece of electronic hardware that can be used as a controller. In other words, it’s a circuit board that can be programmed to accomplish any number of tasks.
The official website describes Arduino as “an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software.” The project originated in Italy in 2005, primarily as a way for students to control a number of projects. Over the last five years this “open source” hardware has grown to cult status. Websites like www.adruino.org have cropped up to support enthralled users who want to share their discoveries, projects and how-to knowledge.
Not sure what “open-source” means? Open-source generally refers to any type of hardware or software that can be used for free. Similar to the Linux programming language, Arduino can be purchased or created from scratch. With your Arduino controller in hand, you can program it do anything from automated beer brewing to building your own hovering drone. The projects listed on various DIY sites are as diverse as the people who have stumbled upon/collided with the Arduino movement.
So, what makes it so cool? The Arduino is highly customizable and can be used as a base for any number of tech projects. Whether you want to direct some blinky LEDs or steer your remote control train, the Arduino board is probably the tool you’re looking for. This is one of those little gadgets that you can use to truly explore your creativity. The Arduino can be pared with any number of “environmental sensors” (i.e. sound, light, weight), thereby reacting to its environment.
Still confused? Check out www.arduino.com, or visit www.instructables.com to see recent projects made with this unique tool. Our interest is piqued, so we’ll be sure to find some way to work the Arduino in to a Piki in the coming weeks or months. Hopefully, if we ramp up our tech skills, we can even score some hands-on time with an Arduino.

You are a very bright person!
Good post and right to the point. I am not sure if this is really the best place to ask but do you people have any ideea where to hire some professional writers? Thx
Great site! I am loving it!! Will be back later to read some more. I am taking your feeds also
Super job on the write-up. Countless thanks for sharing it with us, you must have gone by way of loads of work to complete it so well.
You are a very bright individual!
I have read some good stuff here. Definitely worth bookmarking for revisiting. I surprise how much effort you put to make such a fantastic informative website.
The site is arduino.cc.
