Control a hobby servo

 * 1) Hobby servo motors can be controlled using PWM.
 * 2) They require a frequency of 50Hz and a duty between about 40 and 115, with 77 being the center value.


 * Manual Movements


 * Random movements:

Deep-sleep mode

 * This shut down the ESP8266 and all its peripherals & also WiFi.
 * But not including the real-time-clock, which is used to wake the chip.
 * This drastically reduces current consumption and is a good way to make devices that can run for a while on a battery.
 * You Must connect GPIO16 to the reset pin.
