Just blinking onboard green led.\n\nHelloBlinky is one of the shortest and easily understandable program which illustrates Raspberry PI GPIO programming.\n\n* Here is the blog entry: http://internetofthing.io/post/hello-blinky-first-lesson-in-raspberry-pi\n* Lesson #2 https://github.com/LeivoSepp/Lesson2-HelloBlinkyRedGreen\n* Lesson #3 https://github.com/LeivoSepp/Lesson3-HelloButton\n\n## What is GPIO?\n\n**GPIO** stands for general-purpose input/output and it is a generic pin on a Raspberry/Arduino board. Each pin can be configured to be input or output.\n\n![image](https://cloud.githubusercontent.com/assets/13704023/22621382/13b33e60-eb2b-11e6-9776-cf6ca9691280.png)\n\n## Pin is configured as an input\n\nUse it for buttons, measuring temperature, measuring light,  measuring distance \n\n## Pin is configured as an output\n\nUse it for LEDs, motors, relays, lamps\n\n## Pin identification number\n\nEach pin has its own personal number. This number is used to communicate with the pin. The pin number to use to communicate has an orange background. Do not try to use the numbers with grey backgrounds! It wont work and you will get an error.\n\n\u003cimg src=\"http://internetofthing.io/posts/files/9f2da784-623e-4753-b521-59ea81b6f2c3.png\" /\u003e\n\nRaspberry PI has two special pins which are to control the green and red LED integrated on the board. \n\nThe green LED’s pin number is 35 and the red’s pin number is 47.\n\n## Windows 10\n\nTo set up Windows 10 IoT Core to your Raspberry, please follow the instructions here: https://developer.microsoft.com/en-us/windows/iot/Docs/GetStarted/rpi2/sdcard/stable/getstartedstep1 \n\n## Visual Studio\n\nTo start new Raspberry project, use the Visual Studio template “Background Application (IoT)”.\n\n\u003cimg src=\"http://internetofthing.io/posts/files/acc2be75-7380-42a2-bce4-164157b551a5.png\" /\u003e\n\nIf you do not have this project template, then open menu Visual Studio –\u003e Tools –\u003e Extensions and Updates. From there, click online, search for the string “iot” and install “Windows IoT Core Project Templates for VS”.\n\n\u003cimg src=\"http://internetofthing.io/posts/files/a65a0012-adad-43b7-8bd5-c363cd40d322.png\" /\u003e\n\n# Blinky code and explanation.\n\n\u003cimg src=\"http://internetofthing.io/posts/files/2cfbea38-ea7b-4449-906f-26f92f7e558d.png\" /\u003e\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fleivosepp%2Flesson1-helloblinky","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fleivosepp%2Flesson1-helloblinky","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fleivosepp%2Flesson1-helloblinky/lists"}
