Can anyone tell me what pins on the Arduino Lilypad are power pins? Can any of them supply 5v?
Lilypad's pins are 5V tolerant. Keep in mind that you can not provide more than 5.5V to it, or you will fry it.
Ok thanks. How many power pins does the lilypad have?
Check the documentations. The Lilypad behaves just like any other Arduino that has a 328P on board. Same amount of digital pins, same amount of analog pins, TX/RX ... it's all there.
By the way, I'm assuming you have the regular Lilypad, not the "Basic" version that SFE also carries. That one has less output pins.
