WHILE LOOP EXAMPLE IN C LANGUAGE

Simple example on how while loop works.
Syntax:


while(condition) {}
Condition : A condition is assigned to tell while loop that till when it should continue its loop.
Example to print 10 even numbers.
#include<stdio.h>
int main()
{
int num = 0;
while(num <=10) //Repeat this block 
{
         if(num%2 == 0)
         {
            printf(" %d ",num);
         }
num++;// This simply means num = num +1
}
return 0;
}
Output:

  • 0 2 4 6 8
Description:


  • In this example we first repeat some block of statements till the value of "num" variable reaches to 10.Then we check if the current number is even and print it.

  • while(num <=10) { }- this statement  repeats whatever is written inside its block 11 times.
  • i.e 0 to 10 . When it goes in while loop the 11th time then 

  • if(num%2==0) - This statement means that when number is divided by 2 then remainder is zero. This is simply to check if value in "num" variable is even or not.

  • num++ : This means num = num +1;

TOUCH PLATE BASED DOOR BELL

Title:  Touch plate based door bell  Circuit:  Components: IC 555 Resistors: 1 M, 100k, 330 ohms Transistor: BC547  PN2222A Capacitor: 10n 1 Copper plate : as touch plate. A 6v battery An LED / Ic UM66 Description: This is the simple circuit for touch plate based security system. In this project what basically done is, circuit detects stray voltages produced by mains voltage and electrostatic built  up in the room.If sufficient static voltage is detected by the plate then chip will charge up. Transistor BC 547 or PN2222A is used basically to increase the sensitivity.In place of led just connect IC um 66(melody IC). Applications: In homes, of course. This can be specially used in places like hospitals, when patients need to call doctor by himself.
