= Making Music = * DEVICES: Speaker * THEORY: frequency, amplitude, software lookup tables * TOOLS: frequency counter and/or oscilloscope * HANDS-ON: use switches to make different tones. Make music using notes and note-to-frequency LUTs Your kit includes a tiny speaker [[Image(http://i.ebayimg.com/00/s/MTI4MFgxNjAw/z/iq4AAOSwgQ9Vli0r/$_35.JPG, align=right)]]. You can use the speaker with your Arduino to make sounds and even play music. * [http://playground.arduino.cc/Code/MusicalAlgoFun a music program] * [https://www.arduino.cc/en/Tutorial/PlayMelody music with volume control] * [http://www.instructables.com/id/Arduino-Basics-Making-Sound/ Instructable] * [http://makezine.com/projects/make-35/advanced-arduino-sound-synthesis/ Advanced sound and waveform generator] **Exercises**: * Make a sound * Play a song (use an array for the notes and lookup tables for the frequencies) * Use switches to make an instrument * Examine the signal being sent to the speaker using an oscilloscope * NOTE: later, we'll build a thermain == Advanced Projects == [http://www.tehnorama.ro/wp-content/uploads/2010/06/Arduino-LM386.png better sound] [http://blogspot.tenettech.com/?p=518 text to speech]
