Hey there! My friend has been blind since birth and is currently taking culinary at the college I am attending. The problem is there are no scales for blind people. I need to make a scale that will speak out the weight once it is weighed. I plan on using an SD card and 25 sound files (1-20, 30, 40, 50, point, and grams) so that it will speak out the weight of the item. The only roadblock I have is finding a scale sensor. what would I use? is there a way to translate the data being sent to a display on a functioning scale back into data so all I would need to do is add on to an existing scale minus the display?
Any help would be greatly appreciated
