HiGood night. First please excuse raising an old topic.
Reading this topic I saw that the battery being tested is at the same time the one that powers the LM3914. However I would like to power the IC, through pin 3, with fixed 5v, until the test routine does not use the battery charge.
My doubts are: in this case, the scheme below would be right? Would it be fair to keep the values of resistors, capacitors and trimpots? As for the LEDs, would not they glow too much? Would there be a way to regulate their brilliance through a trimpot? Lastly, would it be okay to connect the negative of the battery to the negative of the 5v source?
