Forum Post: using LM3914 to show battery status - help needed

$

Hello ,

hope I got to the right place.

I'm trying to use LM3914 to show me in 4 LEDs the status of a battery 10-12V (all led for 12V , 1 led for 10 and below)

I have read and use the datasheet - but it doesn't work for me

I'm using R1=1.18K , R2=9.8K , R3=0-50K(it's potentiometer)

can someone guide me and explain what I have done wrong? what I have miss?

Thanks ,
