Thanks Alott All of u Sir.
I got it
Like relay is going to switch on our 220 V while it itself works on small voltage, so working like a switch. got it
Thanks
My Actual Circuit is like this:
http://www.geocities.com/sajidraheem/4.gif
In the place of a, b, c, d, e, f, g pins of 7 segment disp i have used 7 LED's
I'm trying to work the problem out, but still if someone can help, i'll b grateful
I told the same thing to my instructor that our IC's cant work for 220V AC
this ckt will not work for real world appliances but he said, it does.
i am still sticked to my point that IC's are designed to work at 5V DC and Appliances for 220 V AC
I am using a 9 V battery to drive the LED's and IC's. so how can i control 220 V appliance???
and if i use a 220v source then will my IC's work, which only operate on 5V
Actually i m in my very early semesters, i dont know this basic thing.
:confused:
He told me that surely my circuit can, really it can work in real world, but some changes are required. I told his that may be transformers are required, to step up the power, but he said no, something else.
I dont know wut to do..
sorry sir.
i didnt find anything relevant to my circuit at that link]
I just wanted to know, if we want to put an appliance at the place of LED
, what changes are required in the circuit? I am using a hex to 7 segment decoder IC and Buffers also in my crkt.
I'm a srudent of BS Telecom Engineering.
I have done a project of controlling home appliances using Computer.
I use LED's to show the appliances, to control home applinace no. 1 means lighting the 1st LED. i used 7 LED's and implemented it using 7 segment display.
Now our instructor is...
