+Simple Deep Sleep with Timer Wake Up
+=====================================
+ESP32 offers a deep sleep mode for effective power
+saving as power is an important factor for IoT
+applications. In this mode CPUs, most of the RAM,
+and all the digital peripherals which are clocked
+from APB_CLK are powered off. The only parts of
+the chip which can still be powered on are:
+RTC controller, RTC peripherals ,and RTC memories
+
+This code displays the most basic deep sleep with
+a timer to wake it up and how to store data in
+RTC memory to use it over reboots
