摘要

This project that; began last month to simulate a breeze's random playing of suspended chimes has expanded-as all engineering projects! seem to do While the circuit and code presented last month.]! can be limited to the standard five-note pentatonic chimes, in the process the code was structured to allow more that those five notes. Please read last month's article (Circuit Cellar 347, June 2019) | to get some background on wind chimes and the music theory used to document or score how a song is written. By the end of Part 1, you had all the tools to produce random strikes of a pentatonic chime, using solenoids instead of the wind. The aim was to give some relief during those long winter months, by bringing the sounds we(relate to summer's warm tropical breezes-wind chimes-indoors. In the process of discussing the music of wind chimes and having extra I/O available on the microcontroller (MCU), I decided to create a string of chromatically tuned chimes similar to those an orchestra would use. With that in mind, the project could be used to play music as well as soothe the savage soul with random (potentially) harmonious tinkles. With 16 outputs, I can cover more than an octave of chromatic notes. A chromatic octave has seven natural notes and five sharps/flats (the
