In terms of the syntax, 

>your array declarations need "[]" after the variable names; melody1  should be melody1[], etc.
>the declaration of int LSV should be int LSV1; this is the name used in the body of the code.
>there are missing parentheses in if statements in the loop; if (abs(sensorValue1-LSV1)>10 should have a ")" at the end, etc.
> there are missing braces in those same if statements; You need a closing brace "}" before the next if statement.

Hmm good deduction. :-)

I'm going to leave the official due date as the 8th but extend a grace period:

• projects will not be marked late if they are completed before the show at Exploration Place on the 11th
• blog posts for the projects will not be marked late if they are completed before 11:59PM on the 11th.

hey im having a problem uploading pictures to the blog, i get this error

crane1.bmp” has failed to upload due to an error
File type does not meet security guidelines. Try another.

[nick smith]

john has to allow that file type. try saving it as a different file extension like .jpg

[coy anderson]

im just gonna try and put them on photobucket and do it that way

I just added bmp as an allowed filetype for you.

[coy anderson]

thanks, i got them up on photobucket and that allowed me to make the jpeg.

I dunno I think it's pretty much what we talked about. There's a couple of wierdnesses, but nothing serious. Looks like the first thing it's going to do is play all 6 tunes, then it should react the sensors as you want I think. Give it a try! :-)

do i just found out that my whole cube is bad and that with my led
drivers i needed a anode not an cathode.
nooooooooooooooooooooooooooooooooooo
any suggestions for a fast solution

[Seth Landon Schoming]

---sorry if this is a duplicate message, i don't think it went through the first time---

I have successfully interfaced my crazy contraption with my wii nunchuck, however, one of my servos only travels in one direction. I have switched it out, etc. and have concluded that it is the servo that is the problem, not the code... Does anyone know enough about servos to advise me how to fix it?

Thanks guys (and thanks to all who helped me with my torque question before!)

-seth

[nick smith]

it did. i just don't think anyone knows how to repair servo's. have you tried taking it back to the store to see if they will replace it?

[Harrison, John]

I don't understand specifically what you are saying but I understand generally, and am sure we can fix this with the right transistors. Come by during office hours and we'll talk.

Just fyi, when you send an e-mail to the list, it gets delivered to everyone on the list BUT you.  So, that might be why it seemed like it wasn't delivered.

Can you bring your servo to office hours today?  Where did you get it?  What's the part number?  Is it one of the servos from the arduino kits we have?

[Christian Kindel]

What do you mean that the whole cube is bad? Just that all the LEDs
are basically backwards?
