INTRODUCTION

YOU ALWAYS USE THE DOORBELL BUT DO YOU KNOW ABOUT IT ?

The first electric doorbell was a simple circle or square with a button.

PAST

The first electric doorbell was created by Joshep Henry in Brasil in 1830. But before, it was one that wasn´t electric. Nowadays there are some but it is not common. It was a metal that you knock on the door and fullfill the function of the doorbell.

PRESENT

Now we have better doorbell. Now we have doorbells with cameras and speakers . Also if we live in a flat or a residential area in the outside door there is another doorbell whith all the houses and works the same.

FUTURE

In the future I hope its beter .I imaginated like a large button that is in the floor infront of the door and with the color of the floor.

I think its going to give us problems like that is broken frecuently because its going to be stepped on frecuently.

It could be good for some things like if somebody tries to get in to your house it sounds in your house and you know that somebody is there.

CONCLUSION

For me the doorbell is not a invention that is much needed but it is good because it has solved some big problems although it still creates others .
