your first post indicates you want the send the data from a 10 bit A/D using a serial port
if you have a 10 bit A/D in mind, read its data sheet
if you do not, go to digikey (or newark, or mouser, or other distributor website)
https://www.digikey.com/ or
https://www.newark.com/ or
https://www.mouser.com/
my preference is digikey, partly because i think they have a better search engine
find a 10 bit A/d with serial output
read its data sheet
look for the serial port information
read up on the types your A/D supports
google is a good resource for information on various serial formats
the manufacturer's website will likley have application notes on the A/D converter
read those
sketch block diagram of what you want
a box for the analog data, a box for the A/D, a box for the serial port on the A/D,
a box for the serial port on the destination, a box for the destination
label the boxes
label the interconnects - how nay wires, data direction, and any other useful information based on your reading.
reread the A/D data sheet and the serial information
take notes, in your own words, (do not copy the words in the readings) of what each block is supposed to do
then ask again, showing your block diagram and a better description of what you want
