Swedish scientists combine hundreds of VCSEL lasers with optics on a 1cm sized biosensor chip A research team at Chalmers University of Technology in Sweden has developed a VCSEL-based laser ...
I'm returning to an old project today to fix it since it got broken during my recent move. This toy I made for my dog is very fun project where an Arduino controls two servos so they can move a laser ...
Abstract: A multimode fiber (MMF) speckle pattern is proposed to demodulate a distributed Bragg reflector (DBR) fiber laser sensor. DBR light source emits a highly coherent laser, and the speckle ...
Abstract: This paper introduces an Arduino-based color-sorting conveyor belt system that automates object sorting by color. Employing a TCS3200 color sensor, an Arduino microcontroller detects red, ...
