INFRARED REMOTE CONTROL FOR HOME EQUIPMENTS

INFRARED REMOTE CONTROL FOR HOME EQUIPMENTS

This electronic circuit is used to control any equipments in your house by any ir remote control  like tv,dvd,etc this one is good working and i used this circuit to tube lite in my room. it will work properly
This electronic circuit have three parts first one is the infrared receiver unit this consists of an infrared module and an amplifier. second part have an ic that toggles the output on and off. third part is relay used to drive electrical equipments
For adding any load connect a relay in the place of led as per the diagram given below i have used a 12v relay for this work and a voltage regulator IC 7805 is used for the power supply of  receiver and switching circuit

COMPONENTS LIST

Resistors  =100,100,470,3.3k,100k
Capacitors  =10mf16v,10mf16v,100mf16v
Transistors=BC557,BC547
Ir module   =TOP1738
IC             =CD4017,7805(voltage regulator)
LED          =red
Relay        =12v 1A
Diode        =IN4007


PIN CONNECTIONS



infrared receiver module
Voltage regulator IC





Attachment of relay




This is my second circuit and here the receiver module is not TSOP1738. I take this from an old dish antenna receiver, the 10mfd capacitor is replaced with a 47mfd capacitor it increases the time of  LED in on condition.Pin connection of this type module is different from TSOP1738 look at the figure

Fleming's left hand rule

Fleming's left hand rule The direction of force produced on a current-carrying cunductor placed in magnetic field can be determined by this rule. as shown in photo hold the thumb,forefinger and middle finger of the left hand mutually at right angles to each other., such that the forefinger is in the direction of current flow in the cunductor; then the thumb indicates the direction of motion of the conductor.

On off switch

PUSH TO ON AND PUSH TO OFF SWITCH This is a simple single ic switching circuit. this is very useful for many electronic circuits switching function. every positive pulse in the pin no:14 toggle the output pin no:2 to on and off. Transistor BC547 is a driver transistor we can connect an LED or a relay to the collector of the BC547. I used this circuit to my infrared remote control circuit.
