Notes from Frequencies

You can use musical note frequencies in the chart below for the tone function’s f parameter to play music.

Example:

bot(22).tone(1975.5, 500)

This command plays a B6 note for half of a second.  Using this chart, you are able to create songs with the piezospeaker and the cyber:bot.

The notes to the first line of  the Happy Birthday song go in the following order: D - D - E - D - G - F.  Matching the notes with their frequencies, we can make the following program.

Example script happy_birthday.py

This example script plays out the first line of “Happy Birthday”
