Arduino. PinMapping168. Some Caveats: ** Caveat #1 : The reason this trick works is that, unlike most Arduinos, the Lilypad Arduino is clocked by the ATMEGA's built-in oscillator instead of by an additional crystal oscillator circuit.
This lack of additional oscillator circuitry makes wiring up the circuitry a lot simpler, but as a result the chip runs slower (8MHz instead of 16MHz) and its timing is not as accurate. The lilypad bootloader knows how to compensate for this speed difference to make sure all of your delays and baud-rates and other time-sensitive functions work correctly, but the fact remains that the chip will perform slower.

Perfboard Hackduino (Arduino-compatible circuit) Make an accurate Arduino clock using only one wire - NO external hardware needed! How to make an Arduino clock - without using external oscillators or clock chips: (more of my projects on our research website - click the arduino logo top of home page) You will need: An Arduino board (just about any flavor will work fine) and software 1 LED 1 Jumper Wire (Wiring Example Updated Below...)
