Perancangan Display 7 Segment pada Timbangan Load Cell Berbasis Arduino di CV. Standard

Abstract

CV. Standard is a company engaged in the field of digital scales located in Semarang, Central Java. This company serves repairs and requests for making design tools with digital scales. Great Scale type A12E and YHL-1 display are two imported products used and sold by CV. Standard. This tool is a display of electronic scales that display the results of the Load Cell scale on the CV. Standard. But the conditions that occur at this time, the data displayed on the YHL-1 display is not accurate. So the data displayed on the Great Scale A12E display and YHL-1 display is not the same. To overcome this problem, the author redesigned the display system that resembled the YHL-1 display, so that the data displayed would be the same. Besides that, CV. Standard does not need to import YHL-1 displays anymore so production costs can be reduced. This tool uses 7 Segment Common Anodes measuring 0.56 Inch, 1 Inch and I.8 Inch as displays. And use 5V / 1A and 9V / 1A adapters as tool resources. From the testing that has been done, the system can change the function of data sent by the Great Scale type A12E which is in ASCII 8N1 format with 1200 bps baud rate to 9600 bps, so the 7 Segment display is the same as the Great Scale type A12E display.
