Question

This is my project and my circuit. I’ve tried troubleshooting and I don’t know what I am doing wrong. The op amps on the left side are 741’s. And the op amp on the right is 91A731. The mosfet is a 2N7000A. The potentiometer is a 10k ohm. Any insight would be much appreciated!!
And without the analog discovery wires. The bottom right with the long orange wire, resistor, and the two LED’s is my ground.
Design an Instrumentation Amplifier. An instrumentation amplifier amplifies the difference between two input signal voltages while rejecting any signals that are common to both inputs. Your instrumentation amplifier circuit will output to another circuit which will detect when the circuit has nearly zero output and when the circuit has a large output. You will test your device such that when a common signal is applied to the instrumentational amplifier, an LED will light. When the two inputs are different, another LED will turn on. When testing, use d.c. voltages to the inputs. Your design shall meet the design requirements listed below. You will work alone DO NOT DISCUSS YOUR DESIGN WITH ANYONE. Design and demonstration is worth 100 points total. Design Requirements . Design an Instrumentation Amplifier and an indicator circuit using components that are listed on your component inventory sheet. If additional quantities are required, you may obtain them from the ECE Stockroom (BL-432). 2. The indicator circuit wi indicate when an input is common and when an input is not common to one another. In other words, you will need two separate means for indication 3. The indicator circuit shall be adjustable, meaning that an operator can control the parameters as to when the circuit will indicate Simulate your circuit using MultiSim Use the Analog Discovery to power the circuit Extra credit (25%)-Design a sensor circuit that utilizes an instrumentation amplifier. Connect the sensor circuit to your instrumentation amplifier and prove that the circuit operates as designed. 4. 5. 6.

Explanation / Answer

You have taken the connection from Va and Vb fron the board but You forgotten to make them work in circuit as no Connection is made to the circuit. As +( Red line) and -(Blue Line) has to be shorted with row like A,B,C and so on. As they are not shorted to these line. Check this connection and the circuit will start to work fine.
