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 […]
Simple Gate Open/Close Controller Circuit
The simple gate open and close controller circuit is designed to operate the gate through a couple of push buttons manually, it can be also modified for implementing the activation through a remote control. How it Works Referring to the shown, simple gate open, close controller circuit below, we can witness a rather straightforward configuration, […]
