No need to worry if everything is wired right and make sure there are no short circuits or anything that can short out the chip and fry it or anything else of that sort. So now in this instructable I will show you how to build one of these shields for yourself!

It costs almost nothing and takes only about 30mins or so to make it. So lets get started! Start off by attaching the female headers in the center of the protoboard and then put the male headers in the arduino and then put the protoboard on it so as to get the exact position where to solder the male headers.

Then connect the right pins from the male header onto the female headers according to the pin-out Female headers are going to be used to attach the ATtiny and male headers are going to be used to attach the shield to the arduino Then add the 2 LED's and the capacitor and connect them according to the pin-out as well, make sure the capacitor is attached the right way if its a polarized capacitor. This tutorial shows you how to program an ATtiny. Then once everything has been wired up connect it to the arduino and upload a test code to make sure everything works fine Instructions on how to do this on the next step , then once the testing is done you can add some hot-glue around the solder joints to make sure they are firm and don't make any sort of wrong connections.

To program the ATtiny there are 3 main steps; 1 Installing the ATtiny files 2 Setting up Arduino as an ISP 3 Connecting the shield and uploading the code First download this; This download includes the files that need to be installed on the arduino IDE in order to program and use ATtiny boards with the Arduino programming environment.

By following the read-me, make sure that all the files are installed properly. Now once that is done, connect the shield to the arduino and you should see the Heart LED fading at a regular interval. Now once you see the the LED is doing what its supposed to do, then attach the ATtiny to the shield.

So now since you can program and use an ATtiny, why not try use these for all your future projects instead of Arduino's?

The size of them is much smaller compared to the arduino as well which is very handy when trying to put things into small enclosures etc. If you make any projects based on the ATtiny or if you make this programmer, then be sure to upload a picture or a video of it and post a comment below:.

When I first got my ATtiny it took me the better part of 4 hours to finally get it programmed. I went through countless tutorials online that were old and outdated. I was never able to get the correct files from one website. I had to combine the files from several websites before I was finally able to program my ATtiny.

I'm sure it's easy and I'll figure it out in a bit. For now you are still going to have to use the old version of arduino for programming any ATtiny chips.


The goal of my Current and Updated!!! My first i'ble in this series is how to use I will keep updating my i'bles in this series to work with new Arduino boards, IDEs and the like.

Now I've never tested this process on a windows but I know that it works on a mac. It should be the same for windows, just delete any mac content in the zip.

First you need to download the boards information for the Arduino IDE. Firstly, what is ButtLoad?

Once loaded, the system's ready to go - no hardware modifications, existing programmers or bootstrap cables to worry about! Since all the changes are in software, all you need to revert your butterfly back into its previous condition is just reload your old firmware.

ButtLoad is a cheap alternative to the more expensive programmers, and is faster to build. Not only that, but it offers more features than the official AVRISP - and you can always use the Butterfly as a development board afterwards!

Unlike other programmers, ButtLoad allows you to store a complete application into the onboard Dataflash for later retrieval. That means you can program your AVRs without the nessesity of a computer after the initial storage.

Not all the features I intend have been implemented. Because this is a BETA there may will?

This also means that the code is still "rough" in some places. Those who are afraid of a 16 year-old's awful programming shield your eyes.
