  I used one of the Darlington arrays (ULN2003) to make a relay module and tested an OP-amp in my line following robot. Every IC I have used so far works great.

  We counted them, we tested two of them, they work well. Thank you. We also are delighted with the little piece of art you included in the package. We're not sure what it's for, but we have put it up on our notice board, because it is cute.
