Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It’s intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.

Arduino can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators. The microcontroller on the board is programmed using the Arduino programming language (based on Wiring) and the Arduino development environment (based on Processing). Arduino projects can be stand-alone or they can communicate with software on running on a computer (e.g. Flash, Processing, MaxMSP).

There are different types of arduino’s all matching different needs:

– Arduino Diecimila: (for normal use)

– Arduino Mini: (when you heve less room)

– Arduino Lilypad: (for wearable solutions)

The LilyPad Arduino is a set of sewable electronic components, that let you build your own soft, interactive fashion.
LilyPad is a wearable e-textile technology developed by Leah Buechley and cooperatively designed by Leah and SparkFun. Each LilyPad was creatively designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are available. They’re even washable!

The current Lilypad range include:
– LilyPad Arduino Mainboard (schematic)
– LilyPad Power Supply (schematic)
– LilyPad Accelerometer (schematic)
– Lilypad Buzzer (schematic)
– LilyPad Light Sensor (schematic)
– LilyPad Tri-Color LED (schemtic)
– LilyPad Vibe Board (schematic)

The LilyPad Arduino is more fragile and easy to break than a regular Arduino board. Don’t connect more than 5.5 volts to the + tab or reverse the power and ground pins of your power supply, or you will very likely kill the ATmega168V on the LilyPad Arduino. You can’t remove the ATmega168V, so if you kill it, you need a new LilyPad.
Input Voltage 2.7-5.5 V
