DESIGN OF AUTOMATIC DISPLAY BUILDING USING GRAPHIC LCD

Abstract

In the current millennium era, the development of retail business in Indonesia is growing rapidly. This resulted in the emergence of competition in corporate management. Competition is often the price difference of goods. Labels that exist at every price today are still using paper, labels that are in the price installed on every shelf of goods by employees of minimarkets or supermarkets. Problems are often encountered when changes are too many, sometimes employees neglect to change prices on every shelf. This could be a consumer loss, because of the price difference in the price tag listed when making a payment. Based on the problem, required a system to be able to change the label on the price of goods well, by sending data on the computer to input then the data is displayed on the graphical LCD. Without using cables, Wireless connects between computers with LDC graphical displays and simplifies laying of prices on shelves directly. In this study explain the problem solving by changing the price listed on the paper with graphical LCD to be combined on arduino and Wemos as controller between computer and graphic LCD. From this research shows that this system can receive and send data ranging from server to LCD precisely and never happened packet loss.
