I have this 3 - LM3914 LED display that works fine in Bar mode, that I want to change to Dot mode.
The problem is that in Dot mode when the voltage passes the first 10 LEDs it goes blank, because I'm not using the middle 10 LEDs, before it continues to the last 10 LEDs, thereby not displaying whether it is reading a middle voltage, or off the ends of the display.
How do I wire it so that all the middle 10 outputs from the LM3914 only lights up one LED.
Basically the first 10 LM3914 outputs light-up the first 10 LEDs, all the middle 10 outputs light-up 1 middle LED, and the last 10 outputs light-up the end 10 LEDs.
