Inductor 


Inductor also called coil is just loop of  copper wire with two terminals. It is used to store electrical energy to magnetic energy and vice-versa in a circuit. It is measured in henry.



Inductor are used to make electromagnet, transformer, speaker, solenoid and relays for switching.

#How to make wireless spy earpiece for your exams

In this note we will learn about how to make your own wireless earpiece at home easily.  But firstly we should learn how speaker works. You can see the gif (animation) showing how speaker works. As we know that when we apply voltage in the inductor, the inductor acts like a magnet this effect is known as electromagnet and we all know that in every magnet there are two poles(the south and north pole). Continues changing of poles in the speaker produces sound because like poles repel and unlike poles attract. You can see in the picture down below: Because of this effect our speaker produces sound. OK, I hope you have got internal working information of speaker. But till now you only learned about speaker I will tell you more than this. I will tell you one great fact i.e. as you can see the working picture of speaker you might have notice that why the inductor only moving up and down, why not the permanent magnet ? This is because the permanent magnet is fixed in one

MQ-6 Gas Sensor Interfacing with Arduino UNO and LCD

Hello friends , this is my 4th post in blog and today we will learn about "How To Interface Gas Sensor with Arduino UNO and LCD." Before starting we will first understand "What is Gas Sensor ?" Gas sensor is a type of sensor which is capable to sense LPG gases and can give output HIGH or LOW logic signal to Arduino. In this project I am using MQ6 GAS SENSOR but we can use other also so don't worry. OK, lets look circuit in bread-board. By the way you can use pin-13 as output you can connect buzzer or led to alert. I forget to join buzzer in pin-13. Better to put buzzer. For video click the following link:- https://www.youtube.com/watch?v=BH0F8IuXSnw CODE: #include <LiquidCrystal.h> LiquidCrystal lcd(12, 11, 5, 4, 3, 2); int LED = 13;  int GAS_DO = 7;  int STATE = 0;  void setup() {   lcd.begin(16,2);   lcd.print("LPG LEAK SYSTEM");   delay(1500);   lcd.clear();   pinMode(LED,

Reed-switch Interfacing with Arduino UNO and LCD

Hello friends , In this short tutorial I will give you knowledge about "How to interface reed switch with Arduino UNO and LCD."  Instead of reed switch we can use any other switches like tilt switch, push button, PIR sensor or something that gives output as PIR sensor gives( IR Proximity sensor ) and so on. Ok, Lets start, At first we have to learn about "What is reed switch." Reed-switch is a type of switch which is controlled by magnetic field i.e (Magnet). When magnet comes near the reed switch, it will works as close switch and vice-versa. But it is not like a " Hall Effect Sensor " Ok, take a look of this circuit:- We can use buzzer or LED in pin 13. VIDEO:   https://www.youtube.com/watch?v=PxTf_ru6LdM&t=2s CODE: #include <LiquidCrystal.h> LiquidCrystal lcd(12, 11, 5, 4, 3, 2); int LED = 13;   //pin for the LED int SWITCH = 7;   //INPUT pin where the REED-SWITCH is connected int BUTTON_STATE = 0;   //whether s
