+==== 3.3 Results ====
+Apart from the timestamps on the left, the result in the serial monitor should look like this. In the data that the ESP32 prints by itself, it can be seen that the reset occured due to waking up from deep sleep (1). Furthermore, the last serial print command was not executed because deep sleep was activated before that could happen.
+When comparing the time stamps (1, 3 and 4) it becomes visible that the wake up from deep sleep occurred always 1 minute after the last wake up. However, the milliseconds are always varying a little bit. This might be due to the temperature compensation of the DS3231 through which the capacitance and therefore the frequency of the oscillator are changed. So, there might be very small inaccuracies, but they are constantly compensated for by the module, such that the total drift stays very low.
