Title: $50 robot question... RE: LED light...
Post by: Billi on January 30, 2009, 05:50:12 PM

Hi guys,

I'm just getting into robotics and in the process of making my first robot...

I believe I've finished building my micro-controller now and just wondering if the LED light is suppose to come on when I power on?

I checked and double checked my connections... I also don't think I've 'smoked' anything yet..., just wondering how can I tell if the 'brain' of my $50 robot is alive or perhaps dead...

Thanks in advance.

Oh! Then I guess I should proceed to programming it!

I thought the LED would come on after power on like other typical appliances... and thought that perhaps I screwed something up! ;)

Anyway, thanks for your response. :)

Okay, new problem...

I'm using the $34 AVRISP mkII programmer... when I connect it to my micro-controller thru USB, the light on the programmer turned green, but AVR Studio continued to tell me connect failed.

What's up with that? What else can I be doing wrong?

Also, according to an older post: http://www.societyofrobots.com/robotforum/index.php?topic=1045.0 (http://www.societyofrobots.com/robotforum/index.php?topic=1045.0)
ground and v seems to be flipped compared to the schematic I downloaded...

Is this really correct?

I tried it that way and the green light wouldn't even come on. With my original way, the green light would turn on...

But either way, AVR Studio couldn't connect...   help! :-[

Moving this up...

BTW, when we plug in the programmer, shouldn't something show up on my taskbar? Such as when we plug-in other usb devices, we'd need to click on the green arrow icon to stop it when done...

How come the programmer doesn't do this? Perhaps my issue is software related?
