Design And Construction Of A Sequential Device Control Using Tv Remote Control
Chapters: 1-5 | Type: Project
Overview
ABSTRACT
This work is on sequential device control using TV remote control. This device lets one to switch ON and switch OFF up to nine devices sequentially from your TV remote control.
The circuit consists of an IR sensor module TSOP1738, which is equivalent to TSOP1238. The output of TSOP1738 is fed to the trigger input (pin 2) of IC NE555 (IC1) via LED1. IC1 is wired in monostable mode and its output is fed to clock input of IC CD4017 (IC2). All the nine outputs of IC2 are connected to the bases of relay-driver transistors T1 through T9 that controls the loads via resistors R7 through R15, respectively. Relays RL1 through RL9 are connected between the positive terminal of 12V and collectors of respective transistors.
