How To Make Remote Control Switch at Home To ON OFF Light Fan

Hello, In this video we’ll design a simple remote control circuit using CD, or 017, I see. With the help of the circuit, you can easily switch on and switch up light and other electrical equipment, just by using a TV remote. As you can see, I’m controlling this light, just by pressing the TV remote button. Now first URL plays a cd 4017 component on this breadboard. Now you can see I placed a CD module one seven IC on a breadboard. This is a notch of the IC looking at this notch. This is a pin one, and this is a pin 16 with others, we can easily identify the pin configuration of the IC looking at this notch. Now here you can see I’ve connected a pin 16 with the positive rail of the breadboard, they’ll pop this rate connecting with. And I’ve connected the pin eight cylinder. Negative rail of the breadboard. Now I’ve also connected the pin 13 with the native grille, of the breadboard. As it says on the screen. Now as you can see on the circuit diagram. I have to connect pin four pin. So in the breadboard is only connected pins for the pin 15 of the IC. Now I’ll place the clock transistor. This is the transistor which is BCI seven transistor. And this is an NPN transistors will be slightly different transistor.


One more paper that I have played as a PNP and npn transistor. Now if I drill down in this side, then this will be the collet product pnp transistor will turn the base and the emitter transistor. In for this Tc 5.7 and that is in front. This is the median list a base. And this is a emitter. Now, I have to connect these two transistor with this IC here you can see I’ve connected the collector of the PNP transistor with pin 14, and I’ve connected the base of the NPN transistor with been to throw up to 20 ohm resistor here in the schematic you can see this collector is connected to pin 14. It’s a PNP transistor, and the NPN transistor, and I’ve connected the areas with the pin 242 20 ohm resistor here I’ve connected, our PJs Easter across the emitter of the PNP transistor, and the political of the brain.


Here, you can also see in this schematic, the resistor is connected across the voltage rail and the emitter of the PNP cluster. Now this is the IR detector receiver. The pin configuration is the output pin receives a VSP. And this is the ground pin. As you can see in this schematic. Here you can see I’ve connected the ground pin of this IR detector, with a negative Braille and connected the BSP with quality Braille and connected output pin with the base of the PNP transistor. As you can see in the schematic. Now here upon 100 microfarad capacitor across a negative rate at the base of the PNP transistor.


Now the negative rail connected with a negative tantalum capacitor. As you can see, and connected politic terminal of the capacitor, to the base of the PNP transistor. And you can see in this schematic. Now here, connected to 70 kilo ohm raised across the quality rail of the breadboard and a pin 14 of IC. As you can see in schematic. Now here I have connected point one microfarad capacitor. Pin 14 and below the Brit vote. As you can see, which is also indicated in the schematic. The capacitor and under 270 kilo ohm resistor, are connected in parallel. Across the pin 14, and the positive rail of the probe. Now here, connect the anode of this LED with a positive rail and connected the cathode of the LED with the connector of the NPN transistor through a 220 ohm resistor. And you can see in this schematic. A connected emitter of the NPN transistor, with the negative rail.


As you can see, in the schematic emitter is connected with the negative rail. Now here you can see are connected to rail. And these two positive rail details of these two connecting wires. Now certainly ideally we just have to supply five volts across the positive and negative way to check the circuit. No arrogancy are connected. Quality pipe bolt with the polarity rail. And I’ve connected a negative terminal of the DC source with a negative rail. You can use any five volt source like mobile target or any other source so connected the supply or testing purpose. I am using PP mode. So if I press any button. You can see the circuit is on. And again, if I press it, the circuit is off. You can use any button, the circuit will work. Again, I am pressing it, it will turn off. Now we’ll connect to control, 220 volt supply. With the help of this circuit disconnecting the DC source. I’m using these five volt relay knees to is a coil terminal, and these two are the contacts. So when this terminal will get supply, then these two normally open contact with closed and current can flow through terminal. So this is, this will act as a switch. So, let me. Place this relay on the bread.


Now you can see our current terminal of the relay in this manner, connected one terminal of the coil with the podiumed, another terminal of the coil, with the collector of the NPN transistor. As you can see in this schematic, this terminal is connected with the collector the NPN transistor is the terminal is connected with a positive rate now as I’m connecting a relay coil is our diode, in reverse polarity. So let me connect this diode in reverse polarity to connect a cathode with a positive rail and to connect the anode of the diode, with the collector when you know your consumer connected these diode in reverse polarity connected capital. As you can see this is a band aid terminal, which is connected to positive rail and a note terminal is connected to collector of the NPN transistor. As you can see, this is connected in reverse polarity. So now, to connect any electrical load across the common and no terminal of the relay.


And when idiots five volt supply. This equipment will turn on. And when we de energize the coil, it will turn off. So, let me connect a lamb across this in one common contact of the relay. Now, I will need these 220 volt nine watt LED lamps. So whatever to do you can see. Among these two. I got one of the words, and to place these two words clause in, and a common terminology. So does, we can easily input 20 volts or 110 volts float across these two terminals. So here you can see I’ve connected to close the no end of hormone terminals of the relay. And I used this tape for safety procedures to keep these were in place, as this is a 220 volt supply line. So, you have to get purpose required for this circuit. So, I placed this tape. Now what I have to do is to connect up to main supply. Now, to give five volt supply across the positive and negative rail. You can see, after giving the lamps turn on. Now to turn off the lamp, I have to press any button of this room, I can see again to turn on the lamp, I have to press any button. So, I can normally pull these 220 volt circuit is in this TV remote control. So circuit is very easy. If you follow this tape, the emitter circuit. But while making it, please take proper safety precaution for these 220 volts right now as you can see, if I press the button, the circuit will turn on. If I press the button again the lamp will turn off that I can easily turn on and turn off this seat from any corner of the room.
