Practical Tips and Techniques
We will now be looking at simple data logging using a Click PLC with an Ethernet port. Node-RED will be used to communicate to the controller via Modbus TCP protocol. Information collected will be then stored in an SQLite SQL database. A Raspberry Pi 4 single-board computer will be used for the Node-RED collecting and … Read more
The IR (Infrared) remote control is a great way to incorporate wireless control of your project. Infrared receiver modules are simple and easy to use. In this post, we will be connecting the IR receiver to the UNO, and then use a Library that was designed for this particular sensor. In our sketch we will … Read more
