This project can display as a screen by rotating the Led series to cause POV phonomenon
POV Rotating Led using Esp8266-Node MCU and SK9822 Led series
The electrical motors is using a 12V motor which has rpm around 3000
This project contents the wire connection map, python code run on computer and micropython code run on ESP8266.
Then you shold make simple mechanical connection by yourself, and make sure to be safe!!!

1.connect the ESP8266 through webrepl
2.input from Led8266 import *,and you 'll find 15Led trun on with white light
3.turn on the electrical motor to enable it to spin
4.as spinning stably, input Led_start(), the counter'll count and detect
5.run the Led_ocv to send the picture，and it will shinning automatically
