could someone give me/guide me in the right direction for a little project i am trying to do.
i have the output of a transmitter (4-20mA) and i want to use this output to illuminate 3 different LED's.
i am converting this 4-20mA to 1-5volts and what i'd like is for one LED to illuminate when it sees 1v, the other to illuminate at 3v and the other to illuminate at 5v.
You could use an LM3914 Dot/Bar Display Driver. By setting it in the "dot" mode and proper selection of the internal reference voltage and output drivers, you can use it to illuminate your 3 leds (or even more if you like).
