Recently, [Solder Hub] put together a brief video that demonstrates the basics of a Hall Effect sensor — in this case, one salvaged from an old CPU fan. Two LEDs, a 100 ohm resistor, and a 3.7 volt ...
The Quantum Hall Effect was first observed in 1980 by Klaus von Klitzing, for which he was awarded the Nobel Prize in Physics in 1985. It occurs in two-dimensional electron gases found in ...
Hall effect sensors are everywhere right now. Keyboards, game controllers, and DIY kits use them for more precise inputs. But with any newly popular device, it can be easy to immediately jump onto the ...
