A microcontroller is a small computer device by itself that can be programmed to respond on it's input and output signals. As sizes gets smaller with variants of I/O count and computer power, application of microcontrollers on wearables are endless.

Arduino Mega 2560 R3

The Arduino Mega is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button.


LilyPad Arduino 328 Main Board

The LilyPad Arduino 328 Main Board is an Arduino-programmed microcontroller designed to be easily integrated into e-textiles and wearable projects. It offers the same functionality you find in other Arduino boards, in a lightweight, round package designed to minimize snagging and profile, with wide tabs that can be sewn down and connected with conductive thread.
