Problem Statement
In this project, you design, develop and demonstrate a simple working magnetic levitation step up involving one electromagnet and a permanent magnetic object. Matlab/Simulink may be used to study stability of your magnetic levitation set up.

Equipment List

 * 1 Electromagnet
 * At least 1 neodymium magnet
 * 1 Potentiometer
 * Wires
 * 1 Hall effect sensor
 * Aruino
 * Ac Adapter
 * Wire Cables

Project Plan
We plan to use the electro magnet given by our instructor and the AC Adapter to create a levitating magnet. The potentiometer will be used to increase and decrease the magnetic force of the magnet and the weights will be used to equalize the magnetic force and gravitational pull.

Week1 Narrative
The group separated work and thought of ideas and methods to levitate the magnet using gravitational pull and magnetic attraction

Week2 Narrative
Created a presentation and demonstrated how the potentiometer works with the magnet. As we twist the potentiometer, the electro magnet increases its attraction bringing the magnet up.

Week3 Narrative
Started working on the New electormagnet we received and different hall effect sensors to stablize the magnetic levitation. We decided to levitate the magnet through magnetic repulsion and stability.

Week4 Narrative
We received new magnets on Tuesday from Bob. He dissembled his hard drive at home and found some strong magnets which maybe useful to our project. We also received an Arduino board to program and find the polarity of the magnet. The measurement will be in gause and it will be one of a key concept which will help levitate and secure its stabilization.

Week5 Narrative
We coded the arduino board from the original code which was given by the company arduino. We were able to successsfully use the code to find the polarity of each magnet and its distances. We can now use the hall effect sensor and arduino computer program to find the right point which will levitate the object.

Week6 Narrative
We went ahead and took apart the hall effect sensor and located into front of the Electro Magnet. With the hall effect sensor in front, we will be able to measure the polarity of the magnet to the electro magnet and stabilize and find the right point which will levitate the object. We also programed the arduino which will give us different reading in GAUSE which will define the polarity of the magnet. Pictures of the arduino and the codes are attached to the right of the page, and will be updated with further progress and work.

Week8 Narrative
This week, we received help from our professor Jey. The wiring was too difficult and showing him the diagram, we were able to receive help from him. The wiring is being worked on by our professor and meanwhile, I went ahead and thought of many design which can be changed for our main platform.

Week9 Narrative
This week our team went ahead and changed the base format of the electro magnet in order to create a more presentable structure. Instead of previously wiring all over the board and the metal, we screwed in the electro magnet to the metal and taped the hall effect sensor in order to create a clean working electro magnet. Both the electro magnet and the hall effect sensor were not effected by the tape and both functioned correctly.

Week10 Narrative
This week was the day of the presentation in the DH Room. The room was very big and field with all other ENES-100 team presentations. We were able to not only better learn our project but also different ways that the other teams worked around. Our presentation was fairly okay, but was not too great due to not all the team members exactly knowing what to say about the project. It was mistake that we were unprepared and we hope to prepare more for future presentations.

Week11 Narrative
During this week I was not able to come out one of the days of the meeting. After our presentation last Thursday, we brought back the results and outcome of out presentation being not too perfect. With this in mind, and knowing that we will be presenting on next Thursday Seminar presentation, we decide to create a new power point with the preliminary design and the original power point to better perfect out mistakes we made.

Week12 Narrative
Last week of our ENES-100 team presentation and project was this day. This week, we got together and talked/ thinked about the many things that could have worked in order for us to have completely finished the project. Unfortuneately, our parts did not come in till the last minute and we had un-finished project. The presentation on Thursday seminar went great and we were able to impress some of the audience by it!! It was a great semester that i spent with the team, and if given the chance, i would love to work on another project together with many other people.
