Question

Could someone provide me with a guide or example of how to write the report below?

Produce a detailed report on any application of microcontrollers in controller designs for real-life application. Write about the kind of interfaces used for input and output data and also why microcontrollers where used for controller designs. (1200 words)
(Write a report on any implementation of a controller using microcontrollers for real-life application. The report must have details on the application of the controller, implementation of the controller, interfaces used and why microcontrollers are used to implement the controller.)

Answer 1

I am giving u an idea of how writing a report for and just try to follow it and od it in your own words with much more elaboration.It is impossible to write an entire report and copying it

INTRODUCTION:
Embedded systems are now a days ruling the entire life of Human Race.And it is used in many real life application for our day to day work.An embedded system is a computer which has both hardware and software and depending on the work wheather it should be programmable or not it depends.An important part of embedded system is microcontroller.It is the heart of the system,all sorts of work is done in microcontroller.

Here we are going to discuss a a very normal but essential real life example where microcontroller are used that is Washing machine.

MICROCONTROLLER :

In washing machine AT89S51 Microcontroller is used in washing machine.

PRINCIPLE:

According to the weight of the laundary the rotation of bucket the outlet andintel of water into the bucket and the amount of water to be entered into the bucket according to the weight of the load either light or heavy or medium is done by the microcontroller.

WORKING:

Here in a washing machine principle is quite simple .Here after putting the dirty clothes with detergent in the washing machine,we select the mode wheather it is heavy load or light load or medium load.And for how much time we want to the wash the clothes .These two datas are entered into the microcontroller system .This is know as input of Data.And after getting the requisite date the microcontroller weighed the load in the laundary and open the valve of water to get into the bucket according to the weight of the load and even judging in which speed the bucker must be rotated according to the weight of the laundary.After the clothes are washed the sensore detects and open the outlet valve.and when all the dirty water is released then the valve is closed .It is a sequential process which is predefined and is programmed just once.

INTERFACES USED :

A/D converter is used to control the speed of the motor

A scheduler used to schedule the given time of the operation

Pressure sensors are used to know the weight of the load and allow the amoutn of water through inlet and outlet.

Water level sensor tempertaure sensors are also used to check the overflow and the heat generated by the motor while continous rotating

Water leak detector are also used now a days

WHY MICROCONTROLLER USED IN THIS CONTROLLER?

Control and sensing go hand in hand this helps in reducing time and more efficiency for a fixed set of operation in a give time period and even detect the right amount of energy labour required o do work without wasting energy
