I have a simple project that I need help with. I have attached a photo showing the layout. I have a battery attached to a gear motor that moves a magnet up and down slide that is attached to a pole. The motor is setup in such a way that the motor only has to run in one direction to accomplish this up and down motion. I want to setup a magnetic proxitmity switch at the top of the pole that will tell the motor to start and stop when it either senses or does not sense the magnet. My thought is that the best way to accomplish this is with a simple microprocessor with simple code that controls the power coming from the battery. It will run a pattern, Here is a breakdown of what I want to happen in the pattern:
1. Magnet in position 1 with proximity 1 recognizing it - Motor stopped.
2. Magnet in position 1 with proximity 1 NOT recognizing it - Motor Running.
3. Magnet in position 1 with proximity 1 recognizing it - Motor stopped.
I will need to be able to adjust the sensitivity of the proximity sensor so that I can get the magnet to stop in the right place. I need the project completed ASAP.
I think it's pretty easy just the correct way to wire it, the programming, and what chip to use are beyond me. I am hoping to find someone who can work on this easy part because our next step is to include a timer and a remote to the next model and would like to use the same person for the next job.

HI, in the past I already developed littlemunt like this, for sure NOT PROBLEM AT ALL. But I have a question, when the motor is position 1 (motor off) whos start the process? thank you
'm interested in your project i'll use PIC16f84 micro-controller and IRF740 for motor power control.I'll receive half paid at delivery and the second half will be after testing the circuit and its functionality.
