 LED bar graph Tach I know that this topic has been beat to death. I’m looking for a LED bar graph tachometer circuit that will display the RPM like they do on the F1 and endurance racecars. I know that I found a circuit posted before, but I’ve can’t find it no matter what search I use. I know that it had one row of LEDs, I would like it to have two rows that meet in the middle. Any help would be great. Thanks John Whitney Wis X 1/9 | |

| Are you ok, williB? I think that's another thread ... Johnfiat, I think you might be looking for the LM3914. It's a bar graph display driver which gives a linear response output. (vs the LM3915's log output). My search of the archives gave 70 threads which had something to do with the LM3914. You should find something there ... JB
