I made scrollig led matrix using Arduino uno.( refer attached picture)
I'd like to connect ESP8266 ESP-12E WIFI Board to Arduino uno.
So reciving data from wifi, present real time, weather data can be displayed
on the led matrix.
I'm going to upload ESP8266 WIFI code to ESP8266 ESP-12E WIFI Development Board first,
And connect RX, TX to each other's terminal.
Finnaly they will be supplied power to both power source.
If I do like this way, can I see the web site data scrolling on the led matrix ?
Because of remainning old programed data, new data from the website wouldn't be displayed on the matrix,
In this case how can I reflash the Arduino uno's old program ?
