The economical smart fan system, is a fan which automatically adjusts its RPM speed depending on the number of objects

$$in a room. The fan's speed is initially zero, and it increases linearly as a function of the number of objects in the room. The maximum speed is reached when the number of objects in the room

$$This is a mandatory part of this project. Implementing the functionality when the toggle switch is logic

$$is optional and is considered as bonus.

Design and Development

For this project, you are required to design, implement and test the system in simulation using MPALB and Proteus, and then build the hardware prototype for the system. For the software part, you need to program in assembly, and you are encouraged to maximize the use of interrupts, subroutines and hardware timers in your design. Make sure to include detailed explanation for your design and all the calculations that you do

$.$

Project Groups

You must form groups of three to four students to work on this project. We prefer that you form groups from within your own lab session, but if you cannot find a partner, then you can form a group with colleagues from the other sessions. Please fill in the names of your team members using the following Google form by DD

$/$

MM

$/$

YYYY

$.$

$$One form is required for each group. For those who don't fill the form, they will be grouped randomly with each other.

WE ARE NOT RESPONSIBLE IF YOU CANNOT FIND PARTNERS, OR IF YOUR PARTNER IS NOT GIVING ENOUGH EFFORT, OR DROPS THE COURSE!

Important Notes

Start as early as possible on your project, though the project description sounds simple, there is inherent complexity in both hardware and software aspects, so do not underestimate the time it needs, you will have many problems along the way which you will have to resolve!

Never think of buying a model or commissioning someone to do it for you, not only will you get a zero in the project, but also your act will be considered as a direct violation to JU laws and your actions shall be reported as cheating in the final exam!

Code sharing between groups is NOT allowed and leads to

$0$

$$points$.$

If you acquire a part of your software from a book, website, etc, then kindly reference it properly, else it will be considered as plagiarism.

You are only allowed to base your project on PIC

You are free to use any material to build the model and the holding structure of the hardware devices you use. You might use LEGO parts, wood, strengthened cartoon, or even metallic components.

All programming must be done in PIC ASSEMBLY language only; using high

$-$

level programming languages in this project will get you a zero.

Your submitted work must be professional:assemply languch please help me in pic
