The worksheet, sample code and the public domain “Good Morning To All” music file are now available for our LED Birthday Candle Tutorial from April 2015.
This tutorial was remarkably successful given that it was fairly ambitious. We were very impressed at the number of junior-age children who were able to complete it. Possibly the biggest problem was that new breadboards tend to have rather stiff connector holes, and some of the younger children had trouble poking the components into the holes. The solution is to use the end of an unfolded paperclip to push the holes open.
