minicom is just a little terminal emulator program found on various unix type systems. who knows, maybe even on osx. it's intended use was to automate logins to remote systems, so it has a scripting facility to make it easier to navigate different systems' login dialogs.
since i had a little sketch running on my arduino that was capable of accepting commands over a serial connection i decided to use minicom to send long command sequences and repeat them. since then i have made my project scriptable so i can just program sequences into it and have them run automatically. it retains the serial interface, so that can be used either to run individual commands or to start up a script.
there is nothing inherently rgb about the part of the code that generates the pwm, it's just turning things on and off. if you'd like help reusing code i'd be more than happy to lend a hand.
you may also be amused by orgonan
, which uses hardware pwm to generate audio, then interprets itself as a (sic) musical composition. or by the trippy rgb brain machinuino
which is basically a two voice orgonan with six channels of soft pwm driven leds.
