Abstract
Our project is about infra - red remote control. The main function of this device is to transmit the signal from source (transmitter) to a destination (receiver). It is used a IR-LED (infra-red light emitting diode) as a transmitter and 1R RECEIVER MODULE as a receiver This device can be used as a controller or as a switch to electrical equipment.
This device are consists of two circuits. There are a transmitter and receiver. The components used in this device are resistors (fixed and variable), capacitors (electrolytic and ceramic), diodes (rectifier, zener, LED, IR-LED), transistors (NPN), relay, switches and Integrated Circuits (ICs) (#4011, # 4013, LM567C and 78L05). Three 9V batteries are used as power supplies at the transmitter, receiver and lamp.
This circuit will operate after the IR receiver module receives an infra-red light beam from the transmitter. The output from the receiver is connected to the electrical appliances such as fan. lamp and etc. for activated that equipment. In our project, we display the produced output by using a lamp
