The document provides an overview of a workshop led by Andri Yadi on developing Internet of Things (IoT) applications using web technologies, particularly with Raspberry Pi 2 and Windows 10 IoT Core. It covers essential topics such as development paths, example code in Node.js for GPIO control, and various sensor integrations. Additionally, the document emphasizes the importance of cloud connectivity and includes links to resources for further learning and demo setups.

28. Setup
GPIO 5

29. Code in Node.js
var http = require('http')
, uwp = require("uwp");
//Enables Universal Windows Platform (UWP) "Windows" namespace to be
//accessible
uwp.projectNamespace("Windows");
var gpioCtrl = Windows.Devices.Gpio.GpioController.getDefault();
var switchPin = gpioCtrl.openPin(5);
//Set pin as output
switchPin.setDriveMode(Windows.Devices.Gpio.GpioPinDriveMode.output);
var currentValue = Windows.Devices.Gpio.GpioPinValue.high;
//Write HIGH value to GPIO PIN 5, to light up the LED
switchPin.write(currentValue);
uwp.close(); //Call this when all UWP usage is completed.
