    v1 v2  
    44* TOOLS: frequency counter and/or oscilloscope
    55* HANDS-ON: use switches to make different tones. Make music using notes and note-to-frequency LUTs

     7Your kit includes a tiny speaker [[Image(http://i.ebayimg.com/00/s/MTI4MFgxNjAw/z/iq4AAOSwgQ9Vli0r/$_35.JPG, align=right)]].
     8You can use the speaker with your Arduino to make sounds and even play music.

     15**Exercises**:
     16  * Make a sound
     17  * Play a song (use an array for the notes and lookup tables for the frequencies)
     18  * Use switches to make an instrument
     19  * Examine the signal being sent to the speaker using an oscilloscope
     20  * NOTE: later, we'll build a thermain
