  What is the thing in this circuit that makes you confused?
  This is Simple Non inverting Amplifier circuit using OPAMP.

  This is a part of circuit that i design in eagle and it mend to connect the feedback loop with the negative pin of the op-amp as i found in every book that i looked at. but because the op-amp schematic symbol in eagle has the polarity of the op-amp in reverse (ie the positive up and the negative down in the triangle) i connected it by mistake like the picture and i thought that this is wrong and it won't give me any output because i couldn’t find a schematic with the feedback connection at the positive pin and the negative grounded.
  So i thought to ask you to help what to do

  What exactly you want to make? Inverting Amplifier?

  gulielmo

  yes. can you please tell me if i am going to get any output signal from it or do i have to reverse the pins of the chip before solder it on the pcb. it's not a big problem if the output is non-inverted but amplified because i can add an inverter in the next stage
