Weekly Progress Today,I study about how to make a PCB Board by Altium Program And recieve an assignment to make a PCB circuit on this program.For this study I have got a knowledge to make a PCB board.And in afternoon,I and our group has go to senior room to discuss with our architecture senior and we have got more idea that our product will be a refrigerator that can tell us what food is going to be expired and it will work with a barcode. so engineering team have to go to find an information about a barcode such as how it works , how to program it or how to find a device about it. Then, I has found an information that barcode work by a light that emit to the bar code and scan from left to right and recieve the light signal and then convert it into electrical signal then compare with a data base and finally show that information to the user. The step of barcode working : 1. Print part # in bar code. 2. Scan the bar code. 3. Decode the bar code. 4. Send decoded item number to the computer. 5. Bar code Entry and Information system.

Engineering AnalysisStrong Point- This product is kind of work and interesting- This product makes more convinience for people.- This product is useful for the future.Week Point- This product will take much time to make.- This produt is quite hard to make.

Next Week Job- Next time I have to meet with teacher and talk about a eletrical device so teacher will test our knowledge.
