iv123 0:7a352727249b 1 # Building an internet connected lighting system
iv123 0:7a352727249b 2
iv123 0:7a352727249b 3 In this tutorial we'll use the ARM mbed IoT Device Platform to build a complete connected lighting system that you can deploy in your house or office. The system consists of one (or more) extra-bright RGB LEDs hooked up to an mbed OS development board. The lights can be turned on or off by a motion sensor, but are also connected to the internet, so you can change their color. The system uses mbed Device Connector to connect to the internet, and is secured end-to-end.

iv123 0:7a352727249b 5 We'll go over all the steps required to build the hardware, the cloud integration, and the application. At the end of the tutorial you'll have a firm understanding of building complete connected IoT solutions on the mbed IoT Device Platform. You'll also have a cool light.

iv123 0:7a352727249b 7 ## Requirements
iv123 0:7a352727249b 8
iv123 0:7a352727249b 9 We need the following hardware:
iv123 0:7a352727249b 10
iv123 0:7a352727249b 11 * A [development board](https://developer.mbed.org/platforms/?software=16) capable of running mbed OS.
iv123 0:7a352727249b 12 * A way of connecting to the internet. Choose one:
iv123 0:7a352727249b 13 * Ethernet, by using a development board with an Ethernet connection.
iv123 0:7a352727249b 14 * Wi-Fi, by using an [ESP8266 Wi-Fi module](https://developer.mbed.org/teams/ESP8266/).
iv123 0:7a352727249b 15 * 6LoWPAN, by using a [6LoWPAN gateway](https://firefly-iot.com/product/firefly-6lowpan-gateway-2-4ghz/) and a [6LoWPAN shield](https://firefly-iot.com/product/firefly-arduino-shield-2-4ghz/).
iv123 0:7a352727249b 16 * A breadboard, to hook up the components.
iv123 0:7a352727249b 17 * A PIR sensor to detect motion.
iv123 0:7a352727249b 18 * An RGB LED - preferably an extra-bright one.
iv123 0:7a352727249b 19 * For a better effect you can also use a [Grove Chainable LED](http://wiki.seeed.cc/Grove-Chainable_RGB_LED/).
iv123 0:7a352727249b 20 * After building the original application, you can easily swap out the LED for something [fancier](https://www.adafruit.com/product/1138).
iv123 0:7a352727249b 21 * Some jumper wires. Both male-male and male-female.
iv123 0:7a352727249b 22 * Resistors: 1x 100 Ohm, 2x 220 Ohm.

iv123 0:7a352727249b 27 We also need an account on [developer.mbed.org](http://developer.mbed.org/) to access the online compiler and mbed Device Connector.
