Did you ever find any fittings for your flow meters?
Hey @celblazer - did you end up getting the generic arduino boards to work?
Iâm currently trying to get a generic Mega to work. Connects to the PC OK - Arduino software âseesâ the board. I flashed the firmware, which seemed to work fine. But the board doesnât seem to âtransmitâ - even when using the test pin 12 only the Rx light flashes, not the Tx. So looks like itâs not communicating properly.
Never got around to building one. Sorry.
NFC works out of the box if you have a tablet that uses nfc. Otherwise youâd need to wire an nfc reader to your arduino
