This sound controlled lights circuit design is used to control the brightness of the lights attached to it in sync with the sound that is being capturated by its microphone. This electronic circuit ...

In a series circuit, the current passes from the power source to the first light, then the next, then the next, and so on, until it returns to the power source and completes the circuit.

Our lights have an even longer life, at 15 years, than metal halide lamps, which only last about two years. What are benefits for the Lansing Board of Water and Light and Midwest Circuits?

Outside the integrated circuit, other components also require work before we can achieve large-scale quantum computing using light.

This light chaser circuit (music-operated lighting effect generator) comprises five sets of 60W bulbs that are arranged in zig-zag fashion. The bulb sets glow one after another depending on the ...

A novel silicon microchip device slows and varies light-pulse speeds—a function considered critical for the development of photonic circuits based on light instead of electrons.
