A colleague recently made an Arduino-based thermometer to measure how hot it gets in the office. I thought I'd recreate and document the project with the components I have at hand   Circuit  The circuit is based around the TMP36 temperature sensor. It's cheap, easy to use and doesn't require any external calibration. The voltage output is linearly proportional to temperature in degrees Celsius, making the conversion easy to calculate. Any Arduino or microcontroller having at least o ...

Introduction The idea Research Introduction Alright! I've been selected for the The Internet of Holiday Lights RoadTest Plus (or "mini challenge") along with 19 other competitors. In this post, I will describe my submission and what I intend to realise for this RoadTest. The idea My internet holiday lights idea for this Road Test plus is about making a Christmas tree with both classic and modern elements.   The classic element would be the base of the tree, wh ...
