The use of computer in physics experiments simplifies getting data. It also gives a great convenience in calculation and getting graphs that helps interpretation of the results. It's possible to use a computer as a measurement device by correct interface system and software. By this study the physics experiments that can be used in high school physics laboratories are improved. An interface system is used with the experimental devices. As expected use of computer shortens the elapsed time to collect and analyse data, get the graphs and compute the results. The measurements did with more precision and expected results are attained.
