I am working on building a j1939 breakout box and want to add LED indicator lights to Can H and Can L lines. I am trying to figure out how to fully switch a 12v LED on/off based off the 2.5v-3.5v signal change or 1.5v-2.5v change.
I believe I could use a transistor to accomplish this but cant quite wrap my head around the actual circuit design.
Any thoughts or advice would be greatly appreciated.
