Hi there, Ive been recently struggling with this:
What I would like to achieve is this:
Where each bar corresponds to one cell group and also shows its voltage.
Extra question I had was this:
Where I could print these PCB’s? I know it is not the one I need (would need to create a new one)… but I was wondering where do people order them, for example in count of 10?
EU Sources for pcb making would be nice… as Thats where I reside
Anyways, what I mean is - I would like to get extra help to achieve what I have showed in the pictures…
I want to sort of create my own cell meter but my arduino knowledge is lacking…
All I know for now, is that I can use LM3915 can make everything easier to output to leds of bar graph.
Then, using arduino I need to divide voltage for all cell groups I need… as I remember there was something about dividing the voltage till it gets to 5v level, which the arduino can read.
So yeh, if anyone got that far, would be cool if you could confirm the steps which should be taken to create this… Im still not sure what else I will need to program and get before programming and so on.
