Forward rotation:
for i=1,100,1 do
tmr.alarm(0,20,1,function () -- 50Hz
gpio.write(1, gpio.HIGH)
tmr.delay(2000) --Forward
gpio.write(1, gpio.LOW)
end)
end

Lesson17: TWO NodeMCU Communication
The ESP8266 NodeMCU has three kinds of working mode which are “AP” 、“STA”、“AP+STA”.
In this lesson we will use two NodeMCU to conmmunicate with each other. One NodeMCU to be
set as “AP” mode and another to be set as “STA” mode, then establish TCP service between them.
