| Summary: | Infra-red remote-control is a simple circuit that includes two major circuits a transmitter and a receiver. It is useful in electncal instruments. The transmitter circuit consists of 9V D.C supply voltage, Zener Diode , CMOS 4011 , Variable Resistor ( trimmer pontentiometer ) and Infra-Red LED. The receiver circuit consists of 12V D.C supply voltage , Infra-Red receiver module, D.C 12V SPDT miniature relay, LM 567 Low Power Tone Decoder, CMOS 4013 Dual D-type flip-flop, SPDT sliding switch ( for mode select ), and a series 78L05 voltage regulator. This circuit is designed to assist users when they are using electrical instruments. In other word, this Infra-Red transmitter and receiver is like a wireless switch, where the users do not have to move around just to switch on an electrical instrument. The output from receiver can be connected to any electrical instrument such as fan, lamp, radio and etc. In our project we connect the output from the receiver with a lamp socket. |
