This is the code for the Arduino + CC3000 + Relay article on the Open Home Automation website. The article is about controlling a relay via WiFi from an interface running on your computer. The ...

It is very easy to build an “SMS-controlled relay” with the help of a cheap GSM modem module and a small microcontroller board. Here, I’m using the SIM800L and Arduino Nano V3 to develop a nifty ...

Arduino has recently announced two new expansions to their Arduino Pro Opta PLC series – the Arduino Pro Opta Ext D1608E and Arduino Pro Opta Ext D1608S, the main difference between the two is that ...

This research aims to create a Smart Energy Meter that can monitor, notify, and terminate excessive electrical energy use on the Internet of Things (IoT) using the Blynk Iot application as the IoT ...
