Hi All,
Just reading up on the A\D Module of this chip and want to have a go at sampling voltages.
The datasheet for the chip suggests:-
For my first prog I just want to have a pot which I can adjust to get a reading from the module, if I undertand "impedence" correctly does that mean that the choice of pot should'nt exceed 2.5k?
Thanks in advance?
