Beginner : LilyPad doesn't light up

Forum 2005-2010 (read only) Hardware Troubleshooting

I just bought a new LilyPad (Main Board 328) a FTDI Basic Breakout 3.3V and a power supply.
I'm trying to get the on board LED of the LilyPad to light up with the Example sketch (Blink) on the Arduino Software.

Although I get a "done uploading" message (no errors) and the TX and RC LEDs on the FTDI light up, the lilyPad doesn't respond (the LED on PIN 13 doesn't blink).

I'm wondering why; I used this tutorial : web.media.mit.edu/~leah/LilyPad/

Even when I press the reset button, the on board LED doesn't fire up.
Any ideas why?

I'm a beginner so please bare with me :slight_smile:

PS. I noticed that although I order the 3.3V FTDI Breakout, the one I received says 5V FTDI Basic. Could this have to do with my problem?

(This post is sort of the blind leading the blind, as I just received my first Lilypad, too, but since no one else has replied yet I figured it was worth a shot...)

First off: as far as I can tell, the Lilypad should be fine with a 5v breakout; I'm pretty sure that's what I have (although I can confirm when I'm at lab if you want).

Next: I'm apparently not allowed to have my very first forum post contain a link, so I'm going to reply again after posting this with the rest of my thoughts.

I imagine you've already found this, as it's linked from Leah's Lilypad page, but you should definitely go through the troubleshooting steps listed here: http://www.arduino.cc/en/Guide/Troubleshooting#upload

What sort of hardware or technical experience do you have? My next thoughts go toward software debugging, but I don't want to go too far in that direction if you're a professional software developer or something...

My final thought is that you might consider emailing the company from whom you bought the board, especially if you got it from sparkfun (since they are involved in the design/manufacture).

thanks!

does the LilyPad board have LEDs on it (Pin 13) ?

I connected another LED to the Pin 13 and it worked.
Either the LEDs of the LilyPad are defective or I thought it had LEDs when there where none...

Anywho, problem solved.

The most recent generation of lilypad definitely has an LED onboard, and I'm pretty sure it's at Pin 13. Maybe yours is broken (or missing?); how does it compare to the full-sized photo from sparkfun?

In any case: I'm glad you got it working! :slight_smile:

it all looks the same... I guess the LED is broken, or something similar.

Thanks anyway!
