I have added a link to your MultiSpeed I2C Scanner in Arduino Playground - I2cScanner
See the "Interesting Links" section.
But I don't like that link to reply 4.
robtillaart, could you give your Multispeed I2C Scanner it's own place and adjust that link in the i2c_scanner ?
You could add it to the i2c_scanner page, but perhaps that is confusing for new users, that page is very simple now, and that is better for new users.
Another option to edit your first post, and make that the main article and for your scanner.
