Improvement Tutorial Example "Tone2"


The Examples are great to get started. Good job!

I found some mistakes though, and would like to post them here:

In this tutorial:

  1. The text says "Connect one terminal of your speaker to digital pin 9", the example code also writes to pin 9. But the comment in the code says "8-ohm speaker on digital pin 8" and the example-code in the arduino-SDK also uses pin 8. This could confuse beginners.

  2. In this picture: The black wire on the left top side is unnecessary.
