Wave Shield- Uploaded daphc.pde successfully, but no sound/no error msg's

[porrick]

Hi-

I just mounted the v1.1 Wave Shield onto the Freeduino board that I put together in one of the famous NYC Resistor classes I then did the following:

1) formatted 2GB SD card using the format utility recommended on the Ada site
2) uploaded one of the 16khz sample WAV files recommended by the Ada site to the SD card
3) put the SD card in the Wave Shield's SD card holder
4) plugged in a pair of computer speakers to the Wave Shield (also tried over-the-ear headphones)
5) plugged in the USB cord to the Freeduino board
6) successfully uploaded the daphc.pde and the SdReadTest.pde sketch via USB cord

Neither of the sketches produce anything. No sound is coming out of the speakers/headphones and no messages (error or otherwise) are displayed in the Arduino software. I'm using Arduino software v1.0.4 which is set to Board: Arduino Duemilanove w/ ATmega328. I've confirmed that the Freeduino runs the Blink example sketch flawlessly.

Any ideas on what might be wrong? I've attached pictures- please let me know what else I can provide.

Does the Wave Shield require more power than it's currently getting from just the USB cord?

Thanks in advance for all help!

Looks like some potential cold solder joints -- especially that middle-ish pin on the SD card holder, and pin 13 on the shield looks a little iffy as well. Remove the shield from the Arduino and go over each connection with a soldering iron, making sure both the pad and component are heated sufficiently for the solder to flow.

Thank you, pburgess- I'll resolder all suspect joints.

BTW- those white wires were made by stripping the breadboard wires that came from Ada [https://www.adafruit.com/products/153]- are these sufficient?

[pburgess]

Yeah, the breadboard wires should be fine. The soldering at the ends does look a little haphazard, but as long as there's no solder bridges or frayed bits making contact (do you have a multimeter to check with?), they'll do the job.

pburgess- thanks- I'll inspect for bridges/frayed ends. I do have a multimeter- however, I've never used one I'll Google how to do so unless you have any recommended resources. (Thanks for your prompt replies!)

If it has a continuity tester mode (beeps when the probes are touched), that's what you want. Then just touch adjacent pairs of pads on the board. If there's a short between them, it'll let you know. Beeep!

If there's no specific beepy mode for this, you can just watch the display...the value will be zero (or nearly zero) if a short.

It just so happens that we have a Guide To Multimeters on the Adafruit Learning System!

pburgess/ driverblock- Thank you so much for your help- it's playing the WAV file now! All I did was resolder some of the joints and voila!

Time to have some fun with my new working Wave Shield- I'll see you around the Forum!

Thanks again,

Just added 2 buttons to a breadboard which is connected to the Wave Shield- ck out the YOUTUBE vid! https://www.youtube.com/watch?v=AorCL8IYROk

Thanks again, guys!

Nice! You'll soon be tapping away like Futureman

Haha- funky!
