Hello,
i am learning as i go and i have no programming skills here , i am a total noob.
I am installing pressure transducers into brewing kettles one in hot tank, and 2 in my boil kettle.
i have successfully wired and programmed my arduno uno wifi rev2 with on transducer . it works great there.
i need help communicating this data with the raspberry pi 4 and with node-red to take data and use my formulas to calculate the volume in the tanks. what is the best way to communicate with the controllers. usb cable or the wifi
second how do i program the arduino for that specific communiation type.
Thanks for the time to read, and i look forward to the help and the learning .
Cheers
