/*
|
||||
WiFiAccessPoint.ino creates a WiFi access point and provides a web server on it.
|
||||
|
||||
Steps:
|
||||
1. Connect to the access point "yourAp"
|
||||
2. Point your web browser to http://192.168.4.1/H to turn the LED on or http://192.168.4.1/L to turn it off
|
||||
OR
|
||||
Run raw TCP "GET /H" and "GET /L" on PuTTY terminal with 192.168.4.1 as IP address and 80 as port
