If you have a simple Arduino project that uses only a few pins, you might be able to shrink it down to a single 8-pin ATtiny chip. In this video, Matt Richardson shows you how, based on a tutorial from MIT Media Lab’s High-Low Tech Group. The best part is you can use the same Arduino code and development environment that you’re already used to.

More information about this how-to is available at: http://blog.makezine.com/archive/2011/10/how-to-shrinkify-your-arduino-projects.html

    Hi there, I was just wondering where the written instructions and file downloads went, i can’t seem to find them.

    Ok, does it work with an arduino mega ?

  • Peter

    1. can I just take the chip from uno and use itself without arduino board? (Project already uploaded)?

    2. How to power up the chip? Use 5V pin? On arduino 5V is output :/

    Reason I asking I have two arduino and one of them is broken but chip itself is fine (replace it and work)

    Kind regards

    I think the hlt.media.mit.edu link is down.

    good site for the support files

    I tried to override the chip but I always get this error:

    avrdude: Yikes! Invalid device signature.

    Double check connections and try again, or use -F to override

    this check. What can I do?
