The idea was requested by Mr. Ray Strong. Technical Specifications So glad I found this site, […]
How to make simple a LI-FI (Light Fidelity) Circuit
LI-FI is buzzing around the Internet since past few years; recently LI-FI is gained more popularity around the internet and developers. LI-FI stands for Light Fidelity which was coined by Harald Hass. Circuit Objective The objective of LI-FI is transfer data through visible light. Since the bandwidth of visible light is 10,000 times more than […]
