Using your results in step 1, design and build the 2-level voltage level meter in Figure 5. Note that voltage node V₁ in the voltage divider (Figure 4) is connected to the inverting input of one of the op-amps and voltage node V₂ in the voltage divider is connected to the inverting input of the other op- amp. Use the equation in the "Light Emitting Diodes" supplement to determine values for Rlimiting so that the current through each LED (when on) is 10 mA, as specified in the supplement.
