I am new to this forum. I have been out of the electronics field for quite some time and with down sizing in the company I work for I have had a project thrown in my lap. It is a simple light tester that will test the resistance of an object. The window of a successful test is to be .1 ohm to 6 ohms. If the object is dead short or above the 6 ohms resistance, then a Bi-color LED will light red. If the objects resistance falls within the .1 ohm to 6 ohm window, then the same Bi-Color LED will light green. This circuit needs to be accurate and will be used in very cold temperature ranges of around 0 degrees F. I am pressed for time on this project and have been looking over comparator circuits. I would appreciate any input or help in this circuit design.
Thank you,
Scott
