Programming the ESP8266(WiFi Module) To
turn on a LED
Name:
ESP8266
▪ First we need to set up a server and connect
to the WiFi server we just created.
▪ After connection is completed, an IP address
will pop up
▪ Visit the IP address, so control the led
▪ How does the led know to turn on?
▪ When visiting the IP address, the browser
will send a HTTP request to ESP8266.
When ESP8266 read the request, it knows
that user wants to turn on the LED or off.
Pictures
When connected
Successfully, this window
Will show the IP address
You should visit to
Declare PIN D7 as the output
which will be connected to the led
lights.
This is an example of what push button will be like
