MakePython ESP32
Contents
Introduction
Python is one of the most widely used, simple and easy-to-learn programming languages around. MicroPython is a lean implementation of the Python 3 programming language that has been pared down to run efficiently on microcontrollers.
MakePython ESP32 is preloaded with MicroPython, simple and suitable for beginners to learn the basic programming with MicroPython, Of course, users can free to change it to make it work with other platforms such as Arduino/GCC.

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
After saving and clicking run, you can see network config, followed by the IP/netmask/gw/DNS address of the interface:
3.control LED
Enter the IP address printed from the serial port in any browser, with any computer in the same WIFI, to control the LED on/off:
When you click 'ON' with the mouse, the LED will turn on, and when you click off, the LED will turn off：
