Motor Shield doesn't seem to be working

by etharooni on Sat May 10, 2008 6:36 pm

Yeah, Hi. I just got my motor shield at Maker Faire the other day and soldered it just recently. When I plug it in, the LED doesn't come on. Should it? I tried both the DC motor and Stepper motor programs which didn't work. What's the problem?

you should post a clear, non-blurry, high quality, in focus photo of your assembled shield

It's my first successful PCB soldering attempt. As you can probably tell by the soldering, I'm a n00b.

the soldering is mostly good, but there are many sketchy-looking joints

go thru and resolder the points

also make sure you're providing 9V power to the arduino thru the DC plug

Ok, now the LED turns on, but the motors still don't do anything. Thanks for the help so far though!

yes! it worked all along! I just didn't realize that if the jumper was set to USB and the Power Jumper was on, that both had to be in at the same time. It really is an awesome shield! But now I feel stupid!

I killed my Arduino

by etharooni on Tue May 13, 2008 12:04 am

w00t Triple Post!

I was playing around with stepper scripts and boom:

Code: Select all | TOGGLE FULL SIZE
avrdude: verification error, first mismatch at byte 0x0002
         0x5a != 0x37
avrdude: verification error; content mismatch


It shows up on any script I try uploading.

YAY! I killed it! Should I order a new atmega168 or is it something I can fix?
