Recently, I got an esp8266 board and installed
MicroPython on it. It can be controlled by typing command or uploading a python code to it.
from machine import Pin
led=Pin(2,Pin.OUT)//Pin 2 is the on board LED.
The different version MicroPython, the code maybe different.
The OGT UI comes with a demo UI. For testing it, you need download demo python code and put it to MicroPython .
