The easiest way to achieve the goal as my topic says would be fine~
My idea now is like
a. Create a simple website, people who scan the QRcode will link to the website.
b. The Website will collect input to be a table. Maybe i need to write an UI?
c. Use the Excel to catch table from online to window once in a while.
d. My processing code read the excel file and display the marquee.
I’m not sure if it is possible. And now, i have no idea about (a) and (b) QQ
