In the first two posts for switching wie first checked how to process a put request in the Node-RED plugin of the SignalK server and then how to generate it from the Arduino. In this part we approach the other side of the chain using a shield with smart FET’s to switch and observe a …
After we figured out how to send a “PUT Request” to the SignalK-Server and how to process it using Node-RED in the first part, this time we’ll create the PUT Request using an Arduino Uno. Therefore, we have to change the communication from using UDP to a web socket. Additionally we have to receive and …
One of the advantages of a bus system is that there is no direct electrical connection required between switch and load. The load is switched by a power electronics which receives messages by the bus system. An obvious advantage is that the link between switch and load, e.g. which switch switches which lights, can simply …
