ATtiny MCU description:

Corporation (Corporation) announced that its low-power ATtiny 10/20/40 microcontroller (MCU) series, to be optimized for buttons, sliders and wheels and other touch-sensing applications. These devices include the AVR MCU and its patented low-power picoPower technology, is the ideal choice for cost-sensitive industrial and consumer electronics markets a variety of applications, such as car dashboard, LCD TVs and monitors, notebook computers, mobile phones and so on.

ATtiny MCU Series Introduction

ATtiny new microcontrollers with integrated AVR microcontrollers, and include 1KB to 4KB of flash memory, with 32 KB to 256 KB of SRAM.

In addition, these devices support SPI and TWI (with I2C- compatibility) communications, providing the highest flexibility and 1.8V to 5.5V operating voltage

ATtinyAVR using patented picoPower technology, low power consumption. Through software control system clock frequency to achieve the best balance between performance and power consumption, but also has been widely used.


Buzzer:
Description:This is a small buzzer for the LilyPad system. Use 2 I/O pins on the LilyPad main board and create different noises based on the different frequency of I/O toggling. Loud enough to hear inside a pocket but not obtrusively loud.

Please note:This is an inductive buzzer meaning that is will act as a short to ground if you are not actively driving it. We recommend you put both I/O pins to low (0V) when the buzzer is not used. Also, it's come to our attention that washing these buzzers will damage them. Until we've figured out a solution to this, avoid washing any portion of your project that contains one of these buzzers.

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!

RGB:

Blink any color you need! Use the Tri-Color LED board as a simple indicator, or by pulsing the red, green, and blue channels, you can create any color. Very bright output. This is a common anode design - to turn on a channel you simply need to ground one of the R/G/B pins to illuminate that channel.
