Project_2: Web Server Control LED

1.Connect LED

Connect the long LED pin to the end of the 330R resistor, the other end of the resistance is connected to 3.3v,the short pin of the LED lamp is connected to the IO5 of ESP32. As follows:

2.Connect WiFi

Click to download the Socket_LED.py file.
open the file and modify the 'SSID' and 'PASSWORD' to local WIF and password:

SSID = "Makerfabs"     #Modify here with SSID
PASSWORD = "20160704"  #Modify here with PWD
