That will really possible in arduino UNo, i done the part to constant message, but need to do more,

Please find the attached images for reference.

If the data you want to display is on the net, you can easily use ESP8266.

Otherwise you can use the serial (UART) port on Arduino. Ir is really easy to decode UART codes.
