- Thu Jan 31, 2019 2:18 pm #80358 This is the site I quoted: http://henrysbench.capnfatz.com/henrys- ... -tutorial/

The tutorial is for an Arduino but it still uses a breakout board with the ADS1115 chip.

I spoke the electronics expert at work and the IC would be more efficient than the voltage divider but in my case I may have a problem with the power supply to the board.
He also baffled me with science about the voltage divider as I should take the current into consideration - I still have no idea what he was talking about but I think it was to do with resistivity!
