RANCANG BANGUN SISTEM PRINT OUT NOMOR ANTRIAN MENGGUNAKAN MIKROKONTROLER AT89S51

Abstract

The queue number - print out - system use microcontroller AT89S51 has been designed and realized. This Instrument can be exploited as queue number - print out - system on the automatic queue system at the place where queue system needed. The system consisted of hardware and software. The hardware consists of minimum system of microcontroller AT89S51, knob input circuit, seven segment circuit and Epson LX- 800 printer. The microcontroller software in this research was built by using assembly language. This system work after microcontroller is turn on then the microcontroller will do the counter initialization and printer setting. After the initialization and setting process finished, the system will be waiting the counter button pressed, if the counter button pressed, microcontroller will send instruction data to the printer for printing and will represent the queue number counter result at seven segment. In the Epson LX-800 printer will do the printing process suitable with input data from microcontroller. This system have been realized and be able to print the queue number print out and also represent the queue number counter result on the seven segment after the button was pressed.
