Arduino Uno


The Arduino Uno is an open-source electronics prototyping platform based upon both hardware and software. It was first introduced in Italy in 2005 by Massimo Banzi, David Cuartielles, Tom Igoe, Gianluca, and David Mellis. It has the ability to sense the environment and affect its surroundings using lights, motors, and actuators through sensors. The Arduino is powered through a USB cord which is connected to another device such as a laptop or desktop. In order to give the board functionality code must be uploaded through the free Arduino software available online.


The simplest task it can perform is turning on a LED light. The kit comes with about 14 simple projects you can perform such as turning on LED lights, playing a tune such as “Twinkle Twinkle Little Star,” making a motor spin, and having a LED bulb respond to how much light is in the surrounding area. All the coding for these projects is available for free online. The Arduino can do much more though such as tweet, operate robots or radars, hand-motion cameras, create knock detecting doors, or even send a text to a phone.


The Arduino’s versatility makes it great for the market. The device can already be used with other hardware; specifically, Android has developed apps that can be installed and interact with the device. This includes the ability for the app to directly communicate with the Arduino. Android has also developed Bluetooth control which forms a two way communication between the Arduino and phone, and this gives the user the ability to interact with whatever is connected to the Arduino via smartphone. There are other applications such as Wi-Fi controlled RC cars and the ability for the device to control a house’s heating and lighting system.


Some issues users have is installing the Arduino or getting Windows 8 to detect the device. Others have had the trouble of not having their sketch (code) uploaded so that the Arduino would operate.


The Arduino Uno is a cost efficient device at $30 or less depending on where it is purchased from. It can be used by anyone of all ages and is currently helping younger students get immersed in technology earlier. The Guide for the device even states “Sparkfun is an energetic young company seeking to make electronics fun, accessible, and approachable to everyone – from kids in elementary school to PhD-toting engineers.” As boards like these are made the amount on innovations and applications will expand to the common user.
