Designed for M5Stack Atom, AtomS3, and AtomS3R series IoT controllers based on ESP32 or ESP32-S3 wireless SoC, the Echo Pyramid base enables smart voice ...
Description: Using an Arduino or a micro controller, we can generate cool-looking patterns with an led strip containing addressable LEDs. In this case, I'm using an Arduino uno (clone board) and a ...
Lasers, LEDs and light sources are devices that create light. LEDs (light emitting diodes) convert an electrical current into light using spontaneous emission in optically active semiconductors.
Abstract: We propose an optical camera communication (OCC) system with dimming control, employing wavelength division multiplexing (WDM) with RGB and infrared (IR) light sources. The system uses pulse ...
