Hi, I've wrote a program for arduino. The program is for weight sorting job which is to be executed by arduino according to the variable input voltage.
The program I wrote can be found through this link. http://www.flickr.com/photos/22334310@N06/
This is for master arduino which will be receiving variable voltage from digital indicator and the indicator will receive input from loadcell.
The problem is when I try to compile this program and upload to arduino, I get red signs indicating something that I don't understand.
Could you tell me what is wrong with my arduino programing?
Another question is, should the arduino software be installed in the program file only?
