    Engineering Window Detector Circuit Design: LED Activation for Voltage Thresholds

    Homework Statement I think I know how to do this but wanted to make sure before I actually make the circuit. Here's a general diagram: [PLAIN]http://forum.allaboutcircuits.com/image_cache/httphome.cogeco.ca~rpaisley4ComparatorWindow.GIF So as you can see I'm trying to make a window...

    Engineering Electronic circuit, LED turns on if Vin is greater than or less than a value

    I'm assuming it'd be something like the attached (sorry for the crappy MS paint job)

    Engineering Electronic circuit, LED turns on if Vin is greater than or less than a value

    Homework Statement Construct a circuit that turns on if it the voltage provided is greater than 3 volts, or less than 2. MUST USE THESE CRITERIA: i<100mA, only one PS. Fewer than ten components. Homework Equations None that I know of, but we've covered resistors, caps, inductors, and op amps...
