For example, when you are controlling a stepper motor using the RC stepper and you move the joystick on your remote control from left to the right the stepper motor will turn exactly 360 degrees. But what if you want to it turn 720 degrees instead~~, or even 89~~.6? By tweaking and uploading the firmware you can do that.

There are a few assumptions I make on this page: First, I assume you are using a computer that is running windows. Second, you want to spend as little money as possible and not have to buy additional tools. And lastly, you have an Arduino laying around.

When you are installing it, make sure the install path you specify doesn't have any spaces in it. That means don't install it in into your "Program Files" folder. A good place to put it in is "C:\WinAVR"

When you are installing it, make sure the install path you specify doesn't have any spaces in it. That means don't install it in into your "Program Files" folder. The programs that come with WinAVR have trouble running when install in a directory that has spaces in it. A good place to put it in is "C:\WinAVR"
