The remote variable resistor functions as a voltage-controlled resistor whose resistance changes based on an applied voltage.

Here is the circuit of a compact yet inexpensive automatic anchor light integrated with an ambient light sensor that turns it on and off automatically.

Researchers at the University of California, Riverside, have uncovered how to manipulate electrical flow through crystalline ...

Researchers have cracked a fundamental optical challenge: how to control both angle and wavelength of light independently—a ...

Building a quantum computer out of silicon allows the computer’s qubits to be integrated seamlessly with their control electronics, but the control circuits can degrade qubit performance. A ...

One nice quality of life feature is an LDR for ambient light detection, to automatically adjust the neopixels’ brightness. The hackiest part, which we thought was really clever, is the enclosure ...

LED based lighting systems provide an opportunity for data transmission in addition to their traditional use as source of illumination. Brightness control is required to achieve either desired level ...

Nowadays, plenty of sensitive electronic devices are installed in secondary circuits in substations. When lightning strikes a substation and transmission line, lightning currents flow into the ...

To find the right circuit in the electrical panel, you first plug the socket tester into a socket. Then you go to the panel ...

A hearing is set for Tuesday to decide who controls California's National Guard-- President Trump or Gov. Newsom. A federal judge in San Francisco ruled last week that trump broke protocol by ...
