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

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.

Fleming's right hand rule

Fleming's right hand rule The direction of dynamically induced emf can be identified by this rule.Hold the thumb,forefinger and middle finger of the right hand at the right angles to each other as shown in the photo such that the forefinger is in the direction of the motion of the conductor, then the middle finger indicates the direction of emf induced. i.e.towards the observer or away from the observer.

Battery monitor LED

BATTERY MONITOR This circuit makes it possible to monitor the charging process of a battery. After constructing the circuit, final adjustments are simple and the only thing needed is a digital voltmeter for the necessary accuracy. Connect an input voltage of 12.65 volt between the positive and negative connections of the circuit and adjust the VR1 (10K trimmer) until Led 10 lights up. Lower the voltage and in sequence all other LEDs will light up. Check that Led 1 lights up at approximately 11.85 volts. At 12.65 volt and higher the battery is fully charged, and at 11.85 is considered to be at its lowest state. LED 8, 9 and 10 indicate the battery capacity is more than 50%, LED 4 to LED 7 indicate a capacity of 30% - 50% and LED 1 to LED 3 indicate less that 30%. This circuit, with the components shown, uses less than 10mA. Of course you can adapt it to your own needs by making small modifications. This circuit is set for DOT mode, meaning only one LED at a time will be lit. If you ...
