Add keyboard support to arduino

Step Two: Add keyboard support to the Arduino IDE

1. Open the Arduino IDE. It will open an empty "sketch" window.

2. On Windows or Linux: Open the "File" menu, and click on "Preferences." On a Mac: Open the "Arduino" menu, and click on "Preferences."

3. At the bottom of the "Settings" tab is a box labeled 'Additional Board Manager URLs'. Paste this into the box:

   https://raw.githubusercontent.com/keyboardio/boardsmanager/master/package_keyboardio_index.json
   

4. Click ‘OK’ to close the dialog

5. Open the ‘Tools’ menu, click on ‘Board’ and then click on ‘Boards Manager’

6. Type ‘Keyboardio’ into the search box. You will see an entry that says "keyboardio by Keyboardio" click on it to select it, and then click ‘Install’.

Once the install completes, click "Close".

6. Open the 'Tools' menu, click on 'Board' and then click on 'Keyboardio Model 01'. (You may have to scroll through a long list of other boards to get there.)

7. Open the 'Tools' menu, click on "Port > ".

8. If your keyboard is not already selected, click on it to select it. (If there is only one option such as "COM3" try it, it's almost certainly the correct port.)

Next step: Install the latest firmware on your keyboard
