Using the circuit in this experiment as a guide, design a 4‐level LED voltage meter. The LEDs should come on sequentially when Vin = 2 V, 4 V, 6 V and 8 V respectively. Include a fully labeled schematic and all analytical derivations.

to create a circuit which drives a controlled current through an LED with an input voltage, Vref.The design performed here is a low power circuit (at most 15 mA ows through the LED) which will be scaled up to a high powered version (300 mA) for your major project. The voltage drop across the resistor should be large enough for the feedback voltage to not be signicantly e ected by noise. The resistance should be large enough for parasitic resistance...
