In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

As we work on projects we’re frequently upgrading our tools. That basic soldering iron gives way to one with temperature control. The introductory 3D printer yields to one faster and more capable. One ...

Two complementary concepts—automatic code generationand the inexpensive, open-source, single-boardmicrocontroller—have reinvigorated innovation inengineering practice and education. Automatic code ...
