var fs = require('fs');
var button_gpio = 17; // maps to digital PIN5 on the board
var led_gpio = 27; // maps to digital PIN7
var fileOptions = {encoding: 'ascii'};

fs.writeFile('/sys/class/gpio/export', gpio_nr, fileOptions, function (err) {
if (err) { console.log("Couldn't export %d, probably already exported.", gpio_nr); }
