	//Project page: https://github.com/slowmotionprojects/green-education-center

	int pinArray[] = {2,3,4,5,6,7,8,9}; // define the pins that will connect to the relays

	int cycle1LengthMs = 12000; // how long each lamp stays on in the first cycle
	int cycle2LengthMs = 1000; // how long each lamp stays on in the second cycle

	void setup() {
	for (int i = 0; i < (sizeof(pinArray)/sizeof(int)); i++){
	pinMode(pinArray[i],OUTPUT);

Recording simultaneous bi-directional raw audio streams (e.g. calls) on OS X

Steps

Install kernel module to mirror speaker/headphones audio onto input interface
Create a virtual "multi-output" device to pipe audio output simultaneously to speakers/headphones and input interface
Create a virtual "aggregate" device to multiplex output/input audio channels
Record audio file
Blend channels, normalise audio, export stereo file.
