The most important work to archive real-time EtherCAT Master on Raspberry Pi is the real-time capable driver for Network controller, W5500 chip in this case. W5500 is controller via SPI interface, writing driver for W5500 is mostly about working with SPI on Raspberry pi.

This project shows how to take over the controls of the OWI Robotic Arm with the help of an Arduino compatible open-source PLC called the Controllino MAXI, together with Cayenne . The Controllino MAXI provides the physical connections to the OWI robotic arm, and Cayenne allows control of the arm via a web browser or via the Cayenne app on phone thus enabling the control of the OWI Robotic arm from anywhere in the world.
In this project, Author will tell you how to connect your entire house(all the electrical appliances ) to internet so that you can control your each and every equipment from anywhere in the world. When i click "on" for TV it open web address which send some data to arduino just say 1. When i click off for tv it send 2. Accordingly my main server nano board receive ascii code and further transmit it to slave server which trigger the relay connected to tv. as simple as that.
This Wi-Fi enabled Arduino robot can be controlled via wireless communication or used as an autonomous robot. Equipped with an Arduino Mega 2560 R3 it allows for quick and easy changes to the firmware and to provide the most flexible platform possible.
This WiFi controlled mobile development platform robot (with camera) is powered by the Arduino Mega 2560 R3 control board, enabling you to build a robot with autonomous capabilities using the Arduino open-source platform. You can control this Arduino powered robot with a wireless network connection and PC.
