ESP8266 Basic Buzzer Tone

Today a small ESP8266 Basic program to use a Buzzer with the ESP8266 module.

The frequency of two tones can be adjusted with the two sliders
BuzTime is the time between switching to next tone

The picture in this post is of a project
is a sneak preview form a project that i want
to publish next week on this blog.
As you perhaps can see it includes a buzzer and
 a ESP8266 and this program will run on it.
