how to detect sensor position with arduino uno Answered

Hi Guys

recently i started use arduino UNO and with simple programs to read from analogue pins wasn't hard.

now i'm facing a challenge, as i have a sensor mat 16x16 (rows and columns)

i want to read 4 rows and 4 columns

i'm trying to use the analogue pins as input for rows and digital pins from (8 to 11) as output

i want the program to detect the position of the sensing area such as (row1 colum 4, for example) and give me the number that measured over this area.

my code is very bad but i'm trying, specially my background wasn't programming or science.



any ideas will be great.
