Perancangan Alat Pengirim dan Penerima Data Menggunakan Infra Merah Berbasis Mikrokontroler AT89S51

Abstract

This study is to learn about the design of data transmitter and receiver using infra red based on microcontroller AT89S51. The design use two microcontroller, one transmitter that using infra red, one receiver using IC TSOP 1738. Microcontroller is a central of the data process and the central of command, the transmitter with use infra red that the function to send the data to receiver. The sent data is suitable with the data that transmitted, so the infra red have to transmitted with 38 KHz frecuency, because this frecuency is free from the distrub of nature infra red. Has as the display used seven segment that the function as display from the value that sent or the value that displayed on receiver.
