Raspberry Pi or Arduino Uno? One Simple Rule to Choose the Right Board

While I've been doing a lot of playing around with my Arduino Uno, I was also curious about the Raspberry Pi, which is more like a mini-computer that runs a stripped down version of Linux then a microprocessor that executes relatively simple instructions in a big loop. This article gives a good description of the differences, but another one to consider is power consumption, especially if your unit is going to be powered by a battery or other limited source. The Arduino Uno R3 less then 750 mW of power, compared to the Raspberry Pi which uses 3,500 milliwatts. Granted, 3.5 watts of power isn't a lot compared to what you would be running off it like lights, but adds up when your counting every watt.

What is an Arduino?

"Arduino is an open-source platform used for building electronics projects. Arduino consists of both a physical programmable circuit board (often referred to as a microcontroller) and a piece of software, or IDE (Integrated Development Environment) that runs on your computer, used to write and upload computer code to the physical board."

"The Arduino platform has become quite popular with people just starting out with electronics, and for good reason. Unlike most previous programmable circuit boards, the Arduino does not need a separate piece of hardware (called a programmer) in order to load new code onto the board – you can simply use a USB cable. Additionally, the Arduino IDE uses a simplified version of C++, making it easier to learn to program. Finally, Arduino provides a standard form factor that breaks out the functions of the micro-controller into a more accessible package."
