Hi, I wonder if anyone could help me with this. I am wishing to indicate three different voltage levels using the attached circuit. I am looking for LED's to indicate a Low, Medium and High condition, so I only ever want one LED on at a time. I thought this circuit would do this for me, but I have conditions where I can have a Low and Medium LED on, or a Medium and High LED on. Am I doing something wrong or have I made a mistake in the design? If anyone can suggest improvements or other designs I would be very grateful thanks.
John
