RGB LED Voltage indicator for 15 - 10 volts
I would like to make a one RGB LED DC voltage indicator, 15 – 10 volts in half volt changes. At first I thought I would use a bunch of zener diodes, but it seems a bit more complicated than that as on my chart how I want the colors indicated. Any ideas how I can accomplish the circuit? There are probably new fancy things I could use but am not aware of since it’s been a very long time since I’ve made a circuit. I am currently just using an analog panel meter. It would be nice have a colored light indicator. If it could be done.
