Can I also use the NE555P Instead of the NE555N ?
Joshua Casper
Yes, I believe that they are interchangeable for most things, if not all applications.

It seems that they just have different manufacturers.

Here are the datasheets for both if you are interested in going further down the road ...

Thanks for the well-written tutorial!
I was able to complete it with no electronics knowledge. I'm gonna add a 'killswitch' to mine to vary the note lengths!

QUESTION...does anyone know what kind of wave this produces? Sounds like square to me, but I don't have a great ear for that.
Joshua Casper
Thanks for the kind words.The 555 Time IC typically producers a square wave. So, you are correct in your assumption. However, you can smooth it out a bit quite easily if you do a bit of searching online .
