A circuit always has a battery (cell) but it can also contain other electrical components, such as bulbs, buzzers and motors. When drawing circuit diagrams, rather than drawing detailed components, we ...

For simple circuits, it’s easy enough to grab a breadboard and start putting it together. Breadboards make it easy to check your circuit for mistakes before soldering together a finished product. But ...

Team discovers fast, simple way to create two-dimensional electronic circuits that could potentially lead to a new generation of electronic devices. When Northwestern Engineering's Erik Luijten met ...

Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...

Open-collector outputs are useful for transmitting buffered digital/pulse signals to the external world when high drive is needed. In harsh operating environments like automotive systems, however, ...
