UPDATE: I ordered a new ATMEGA for my uno and it is now up and running again. I had got to thinking to figure out how I had fried my chip and I'm thinking when I powered it up I must have had something conductive underneath it, without realizing it, which shorted the chip.

Thanks again for all the help and I am glad I can get back into things. I attached a photo of a nice little holder I also got for my uno and breadboard from sparkfun.com

Well thanks a ton for your help and patience with a newbie like me. I saw that adafruit has programmed processors so I'm going to get one of those and see what happens.

Thanks again!

Yes. Both the power and L LED stay lit. L does not blink when pressing reser.

Im used to calling the L pin 13 LED based on tutorials I have done. Sorry for the confusion.

With nothing connected to the board (except a USB cable) and the board powered by USB, is the green ON LED lit?

When you click the RESET button does the L LED blink quickly a few times?

Power light comes on and the pin 13 LED comes on when powered up by USB as it should.

When I press the reset button nothing happens.

Thank you Coding Badly and Lefty for your help. The loop-back test was successful but I am still unable to upload any sketches. What would that narrow down my issue to? Is my ATMEGA328P-PU bad?

My mistake. I understand now.

How would I go about connecting to my terminal application? I am not familiar with this process

...and a serial connector.

Why?

I'll have to look more into this and a serial connector. Thanks.

Hi all. I know this has been a common post but there never seems to be a definitive answer other than following the troubleshooting guide.

I have an Arduino Uno and I have been programming it tthrough my MacBook Pro. I bought the Uno on Saturday and it has been working great including today. A few hours after making a small led project I plugged in my power adapter in to play around with it again and nothing happened.

The power light turned on, pin 13 led turned on and thats about it. I pressed the reset button and again nothing happened. I decided do hook it back up to my computer to re-upload my sketch to see if that would help and that is when I got my error.

I went through the trouble shooting guide, tried pressing reset during different times of the upload and that didn't help either.

When I do upload (including the simple blinking sketch) the RX led blinks three times then a few seconds later the error comes up about the programmer not responding.

Im at a loss and disappointed that this has happened especially because I've been taking good precautions with it.

Has anyone been able to fix this problem or know what the issue is?

Thanks
Jeff

I was given one for Christmas this year and assembled it that night. I love it! Once you learn all of its capabilities it gets even better.

Bleeplabs also provided the Arduino script to encourage customizing.  Once I become more familiar with Arduino I hope to be able to change things up a little bit and see what happens.

wait, did you order the starter kit for arduino?

I bought the Make Getting Started With Arduino Kit which included Uno and I bought the book as well.

All- I highly recommend the "Arduino Cookbook." It has a lot of excellent circuit and sketch examples that range from beginner to advanced.  You may not need to hack a Wii Nunchuck, but you may someday!  Anyway, even if you don't, it's very cool to see how to do it.

Thanks for the recommendation! That'll definitely be my next book.

Hey jeffu, hows the book helping you understand arduino? Im neew to arduino also so im debating ordering this book also.

It has taught me more than I thought. You'll learn about the basics in the hardware and software. Then you get to see it in action with simple LED circuits. Definitely worth getting.

I recommend that you type out the sketches instead of copying and pasting. That has helped me a lot.

Thanks for the help! It makes much more sense now!

 

Hi all, I am brand new to the forum and to arduino. I am currently and quite successfully working my way through Make's Getting Started With Arduino book until now. I am on example 06B and I am having difficulty with setting up the circuit. Based on the sketch it is an analog setup but the book says to set up the LED circuit based on figure 5-4 which uses the digital pin 9.

Can anyone give me direction on how to properly set up this circuit?

Thanks!
