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
