This one has a lot of functionality and could be used with a rev bar to provide al ot more info to the driver.
Another LED/Arduino Rev Bar Project
This one includes a pretty detailed look at SimHub’s Arduino programming and config.
Arduino RGB Rev Lights for SimHub
Most basic project for this type of thing I’ve found . Provides a good foundation from which to move on to more complicated things.
Sim Racing Wheel Settings for Thrustmaster TMX, T300 and Logitech G29
I bought a Thrustmaster TMX a few years ago and was disappointed in the force feedback in all the games I tried with it. Some were practically unplayable with the default settings. I quickly learned how to properly configure the force feedback settings to get the most out of the wheel. I picked up a Logitech G29 and found it has the same issue.
More recently, I bought a Thrustmaster T300, which is a significant step up from the others. Even with that, though, I see the default settings in a lot of games still aren’t that good.
