Editor’s note: Last fall, EEWeb announced its inaugural design contest, sponsored by Arduino and Altium, to develop an imaginative and innovative design project of a motor control system with the ...

Researchers were able to control the behavior of various light frequencies that passed through a specially designed cavity. The successful experiment can pave the way fiber optic advances that offer ...

Engineers built a nanoscale optical device that uses voltage to control light's phase and intensity, advancing quantum communication and compact optical technologies. The device, developed by ...

Generating a freestanding 3D hologram would require extremely precise and fast control of light beyond the capabilities of existing technologies, which are based on liquid crystals or micromirrors. An ...

NYU researchers have found a way to use light to control how microscopic particles assemble into crystals, effectively turning illumination into a tool for shaping matter. By adding light-sensitive ...

The project uses an Arduino to control a bank of four independent RC servos with a PC using a USB cable and a modular Arduino-python software stack. The device can be a great starting point for a ...

Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...
