I am buidling this circuit to amplify a signal from a analog sensor. But for some reason, when I build the circuit on a breadboard I get 0v on the output of U1. The output of U2 works fine, so there is a voltage at the + input of U1. The - input of U1 has 0 v as a result of the output, so there is a voltage difference. The wiring should be right and when I simulate the circuit, it seems to work fine. Does someone have an idea where it goes wrong?
