Alat Pemberi Informasi Pemberhentian Kereta Api Secara Otomatis dari Stasiun Tebing Tinggi-Medan-Tebing Tinggi Berbasis Mikrokontroler

Abstract

The design of railway dismissal alarm automat ically from Stat ion of Tebing Tinggi – Medan – Tebing Tinggi based on microcontroller is a based on the lack of informat ion to the passenger of railway. This dev ise is made to prov ide the passenger of railway with any informat ion either in sound or let ter. This dev ice is consist of any microcont roller ATMega 16 as led controller, sound recorder as output and aligning by IC LM339 as comparator and sensor using prox imity sensor. The results of test ing indicates that this dev ice is operated successfully. This is indicated by led and ISD2560 that prov ide the informasi automat ically according to the designed program. hedesignofrailaydisissalalarautoaticallyfroStationofebinginggi–edan–ebinginggibasedonicrocontrollerisabasedonthelackofinforationtothepassengerofrailay.hisdeviseisadetoprovidethepassengerofrailayithanyinforationeitherinsoundorletter.hisdeviceisconsistofanyicrocontrollerega16asledcontroller,soundrecorderasoutputandaligningbyI339ascoparatorandsensorusingproxiitysensor.heresultsoftestingindicatesthatthisdeviceisoperatedsuccessfully.hisisindicatedbyledandIS2560thatprovidetheinforasiautoaticallyaccordingtothedesignedprogra
