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.

any help - i would be very grateful

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).
