#149

In this video, we look into the deep-sleep functionality if the ESP32, and we are interested if and how the deep sleep works, especially because the ESP32 has a so-called ultra-low power coprocessor. This fact promises new possibilities.
- We will deep-sleep the ESP32 to save lots of power for our battery-operated devices
- We will use three out of four sources for wake-up:
o The timer
o Two possibilities of external wake-ups
o Touch pads
- We have a look at the available (and sometimes strangely named) ESP-32 pins of the WROOM-32 module
- We use RTC memory which survives deep-sleep
- And we calculate, how long the ESP32 can deep-sleep compared to the ESP8266
