I'm real lame at design but I enjoy trying so now I'm actually going to ask for help.:surprised I've been trying to make a custom indicator for my truck to make it more tech cool. I want to take two values from pressure sensors and output it to a digital readout of one sensor and a cascading LED bar for the difference between the two sensors. All this in a package about 2"x2"x4" I want to use it as a filter health check. It should be fairly simple but I'm just not getting it. Anybody out there got some ideas?
