It's been quite a long time, when I’d first posted this RPi sample. Time passed, I'd gathered some feedback form the community, took into account the comments, and this sample is ready to be published at Instructables for the public interested in microcontrollers and the Internet of Things.
What does this example show? How easy, in just a few hours, you can build your first IoT fun project. Building a remote temperature sensor and a remotely controlled LED can be a very good starting point.
It involves replacing LED with power relay and controlling light in your room, adding humidity sensors and, say, light sensors to better monitor the environment and report everything on your mobile device.
This sample can work on virtually any embedded linux board that has Python and 1-wire kernel drivers. It’s possible to connect a number of 1-wire devices to the same line.
You can check the video and follow the 1-6 steps instructions.
