Magnetic Polarity Detector Circuit using Hall Effect Sensor We all know that every magnet has two polarities, i.e. North Pole and South Pole, whether it is neodymium magnet, ring magnet or disc magnet. We also know that opposite poles of a magnet attract and same poles repel. But it is hard to say that which one is south pole and which one is a north pole, so to detect the poles of the magnet, here we will build a simple circuit.… |

DIY Breadboard Power Supply Circuit on PCB A Power supply unit is a very commonly used tool by most engineers during the development stage. I personally use it a lot when experimenting with my circuit designs on Breadboard or to power up a simple module. Most of the digital circuits or embedded circuits have a standard operating voltage of either 5V or 3.3V, so I decided to build a Power supply which can supply 5V/3.… |
