  • Hi. Please can you post the schematic of the 4 (or more) daisy chained LM3914? Thanks…

  • I am struggling with the function R(adj). Why is it sometimes tied to ground and other it has a voltage divider? Also in the cascading example it seems that the R(hi) is tied to ground on the bottom chip, and it sends its R(Lo) to the other chip.

  • How were you able to connect the bar graphs to the power rail and keep them next to each other? When I try it there is a gap between them.

    • Heh, yeah…darn that gap. I ended up bending the legs that hit the gap 90° over, and wrapping them around the next leg over (for a temporary solution, soldering for more permanent).
