How To Make Laser Security Alarm System
We don’t want to design a simple layer, security alarm circuit, by using a PC 547 transistor and India. Does that it is very simple. If you follow this tape, you can easily design it within five minutes. As you can see the operation, if something of laser light, then it will automatically turn on, and it will start a budget. But before starting I would like to thank you in cse.com for sending me the components. You can join the affiliate program of lcac.com and earn commission by sharing their product link all the details given in the description. It will encourage me to make most useful videos. So, let’s get started. Here you can see the schematic of the latest security alarm circuit. First, are in place the BC 547 transistor. And if I want to identify the pin configuration of the BC 5.7 transistor, then it’s an NPN transistor, if I place the car portion in this side, then this will be the collector, then middle terminal is a base, and this will be the emitter. If I placed a core portion on the transistor.
In this side here can see I placed a transistor on a breadboard. Next, I will connect the alien across the base and emitter of the transistor. As you can see in the schematic. Here you can see, I’ve connected this earlier, across the base and emitter of the transistor flow I will connect this 39 kilo ohm resistor across the base and empty pin on the breadboard. Here you can see I’ve connected this 39, k stir across the base of the transistor and empty pin of a breadboard. You can see it in the schematic. Now, I will connect already Braille of the breadboard. With this 39 clone resistor. As you can see, are connected the positive rail of the breadboard. With a 39 K resistor. You can also see in this schematic. This is a 39 kilo ohm resistor, which is connected across the base of the transistor and the positive rail. As you can see in this schematic. Now, I’ll connect this LED across the polity Braille and a collector of the transistor. As you can see in the schematic, it is connected across the positive rail and the collector of the transistor.
So, I will connect the anode voltage rail and cathode data collector of the transistor before connecting to identify the anode and the cathode. So, this longer lead of the LED is anode. And this is the cathode of the LED. So I’m connecting the anode, with the positive rail of the bridge. And I’m connecting the cathode winder collector of the BC 547 transistor. Here you can see, I’ve connected the anode, with the polity brain, and see. And I’ve connected the cathode with the collector of the VC 547 transistor. Now I’ll connect the emitter of the transistor, with a native rail of the breadboard. As you can see in the schematic. So with the help of connecting words and connecting the negative rail of the breadboard. With the emitter of the transistor. As you can see, I’ve connected the emitter of the transistor, with a tube rail of the breadboard. Now if we want to connect a buzzer in this circuit, then you have to connect parallel to do is led to connect the positive terminal of the buzzer, the anode of the LED and negative terminal of the buzzer.
With the collector of the transistor. As you can see in the schematic. So this is a positive terminal of the buzzer and this is a negative terminal the buzzer. Now with the help of these two connecting words, I will connect the buzzer in the circuit hesitancy. Now I will connect this positive terminal. With this red connecting word, and I will connect a negative terminal of the budget, with this yellow connecting verse. No circuit is ready to supply five to nine volt across these positive and negative rain. So here I will need an end goal. You can also use mobile charger. Instead, so I’m going to connect this across the positive and the negative rate of the breadboard. First, we’ll double sided tape, a nine volt battery on the brain, so that it does not smoke.
Now, you cannot see a positive terminal, with a T brain, and negative terminal, with a negative rating. Now if I placed my alias, you can see this as it is on either remove my finger. It inserted will have. Now I have to turn off to show the operation of the circuit. You can see the circuit is down on, as there is no laser light on this alien. So, I will use this legend. If I play a little light on earlier, you can see the circuit is in off mode. If something upsets you can see. Again, if I could turn the light on earlier. Does our kids, turn off. Does this kid four. Here you can see this is the laser. And this is a India circuit. If something absurd the laser light on the circuit and buzzer will start like that. Again, if something upsets the laser light, it will start the buzzer.
