The city says its "Safe and Bright Residential Light" program promotes safety and helps people light up dark areas like alleys and sidewalks. The Democrats who voted against the War Powers Resolution ...

There have been many questions about what direction Arduino would take after being bought by Qualcomm. Now it would seem that we’re getting a clearer picture. Perhaps unsurprisingly the ...

Exceptional points (EPs) in non-Hermitian systems offer a strong response to perturbations, offering a promising platform for sensing. By using a third-order EP of coherent perfect absorption, here, ...

Abstract: This paper provides details about the design and operation of a Collision Avoidance System in smart cars, with the Arduino board as the central control unit, interfaced with an ultrasonic ...
