I have a question about reading Sensor datas with Node-Red and the Raspberry Pi.
I watched some Youtube Videos, and the most of them have the Grove Pi addition to connect there Sensors.
Now i want to ask if i need this Grove Pi or can i connect the Sensors directly with the Raspberry Pi and Analyse the Sensor Datas with a Node-Red flow.
Some of the sensors only have an analog output so i would connect a ADC MCP3008 to the Pi. Do this also work with Node-Red?
Would be nice if you can share a tutorial i can read/watch, how i connect the sensors / ADC with the Pi and how i can read the datas from it. (If something like this exists.)
