title: Arduino Data Logger Shield is incompatible with many devices
body: <p>I got a Data Logger Shield <a href="https://www.amazon.de/AZDelivery-DatenLogger-Data-Recorder-Logger/dp/B01NATCT7N/" rel="nofollow noreferrer">like this</a> for my Arduino. It works like intended most of the time, but I recognized that it is incompatible with many other devices for an Arduino. For example the small 0.96 inch I2C OLED displays <a href="https://www.amazon.de/AZDelivery-Display-Arduino-Raspberry-gratis/dp/B074N9VLZX/" rel="nofollow noreferrer">like these</a> or an analog hygrometer module (a sensor for measuring soil moisture) <a href="https://www.amazon.de/gp/product/B07V6M5C4H/" rel="nofollow noreferrer">like this</a>. All libraries are updated.
  The displays are simply not showing anything and the Arduino does not get any input from the sensor with the shield on, without both devices work just fine.</p>
  <p>Maybe my Arduino or the Data Logger Shield is faulty, I can't rule that out, but I know from a friend that encountered similar problems.
  It also could be, that the shield just blocks certain data channels or similar, that I just know nothing about.</p>
  <p>I would be grateful for a solution, as this stops my latest project from continuing as planned.</p>
