Part of any self-respecting Smart Home, smart relays are useful for switching and monitoring loads that do not plug into an outlet. This also makes them a lot more integrated, and thus, a long ...

Abstract: Reducing the contact bouncing of electromechanical relays is a key ingredient to increase their switch reliability and overall lifetime. For this reason, this paper presents a control system ...

Schematics diagram + PCB diagram (KiCAD 9) and case 3D model (Blender) are also provided. This project is a work-in-progress. Based on the well-known TransistorTester work of Karl-Heinz Kübbeler.

This project demonstrates Li-Fi (Light Fidelity) communication between two Arduino boards using visible light for data transmission. Text data is transmitted using an LED and a 4x4 keypad on the ...
