title: Connecting Arduino to PC without powering it
body: <p>I'm doing a project with solar cell which is connected to battery. This battery should power the Arduino (some sensors are attached to it). At the same time, I need to keep the Arduino connected to my PC to finish my code depending on the values coming from sensors. The problem I'm facing is that the Arduino is taking power from the PC, and I don't want it to do so.</p>
  <p>I know that the cable is for power and data, so I searched for a data-only cable, but it is not available in my region. Is there is any way to disable the power coming from PC?</p>
