hi
you should pase the numbers on your computer first, and then send a header with the number to the Arduino:
e.g.
T2696 ( total visitors 2696)
H4777 ( hits: 4777)
If I had to do this in a hurry I would just write a max patch to open the file with the stats, parse the info and send it out over the serial port formatted. PD would also do it OK. You could hack Arudino2Max to send this data, look for the "R" in the MAX patch that gets sent as a request, and append the data. Then in the Arduino, look for the loop identifying the "R" and change the part that follows to read the data received over the port, and then display it on the LCD. Clunky but it will work. The programmer types in here will have better ideas.
