Hello. we are looking to prove a proof of concept. We want to open and close a door with a stepper motor and a Arduino. The idea is tha we need to have the door to be safe. How can we make the steper motor to stop if some one puts their hand between the door and the frame? we cannot use IR sensor or anything on the frame of the door. I was wondering if somehow we can read when the motor is beeing forced and use that to stop the door. If you suggest using another motor or method we are open to suggestions. So basically this job is as follows. We need to decide which components to use, then we need to open a door the size of a show box and make the door detect if there is an obstacle. if the obstacle is there, the door will open. Remember we cant use sensors on the frame of the door and we need to make it as simple as possible. here is the door we will be opening and closing. the stepper is attached to the door axle, so the motor will move the door from the pivot of the hinge. motor we plan on using. [login to view URL] our budget is 1200 dlls. PLEASE: read the full description before applying. then answer this questions and send them when you apply ( on your cover letter) -Name -Country -How good is your english from 1 to 10 ( spoken and written) -how meany hours a day can you work - programming language you know -do you have a arduino uno and a stepper motor? - if you have a stepper motor is it a regular stepper or a stepper with an encoder? thats all.

Hi My name is Ali. I am from Turkey. I fluently speak English ( speak 7 writing 7). I can work 5 hours programming per a day. I have uno and high torque step motor without encoder but i have dc motor with encoder. Amper measuring will bring solution of the project. High torque need high amper. I am applying from phone so pardon me if any mistake. All the Best, Ali Serbetci

Hi, It is possible to control door motor force by reading the current used from motor. You can use motor driver which has current sensor output and microcontroller will stop motor when current exceeds limit of amperage (motor force). This happens when there is some obstacle on the door. I can do motor control for your project based on Arduino platform. I will select motor driver module and I will do Arduino program Please send details of door mechanical construction. Regards.

Hi. My name is Alex, I'm from Russia. I'm professional programmer/electronic hardware developer with experience over 20 years. There are no wonders in our world, so that we can accomplish your task in only two ways: 1) Measure the step motor's current. 2) Measure the step motor's speed but we need encoder in this case. My English is 7 from 10. 6 hours per day. c/c++/c#/vb.net/Delphi/Assembler yes, I have Uno and different step motors and drivers. But I don't have step motor with encoder. Regards, Alex.

Hello, Name : Kadir ILKIMEN Country : Bulgaria English: 8 for writing, 5 for speaking. I am planning the work time according to the projects. I can work less or more according to project's needs. c/c++, javascript, python... Currently i have a few arduino ( uno, mega, nano etc.. ) Currently i have one hobby grade stepper motor and one nema 17 stepper motor. I can buy materials if required. I am experienced on stepper motors. I think you should switch to a servo motor or some motor and end switch setup. Expensive industrial grade AC servo motors not required. You can use dc servo motors with encoder. Here is why : Stepper motor drivers tend to increase current when they are forced to stop. Drivers without encoder simply cant know if motor stopped or not. Encoder supported Stepper drives increases the current if motor forced to stop. If they cant keep motor on the desired positioning, they activate error functions. So, you have to measure current of the motor and stop the motor if motor try to draw more current than normal operation. That means stepper drivers are doing absolutely opposite things what you required. There is DC motor drivers. Some of them may support current sensing. or you can use a seperate dc motor driver and a current sensor for arduino to understand if the motor try to draw more current than required operation. I would like to talk more about the project. See the required door and suggest options. Thanks, Kadir.

Hi, few questions please 1. What is the expected reaction time of the system for door retracting? 2. What are the door dimensions and angular velocity it moves with while closing/opening? 3. What happens if there is a blockage while opening? 4. How many steps does the stepper have to close before it is blocked by the obstacle? 5. I hope we can have sensors ON the door at least? I have an idea in mind once you are able to answer my above queries which we can discuss. Good luck. -Name- Saikumar -Country- India -How good is your english from 1 to 10 ( spoken and written)- 8/10(BEC higher certified) -how meany hours a day can you work(1hr weekday, 3hr on weekends, open to discussions anytime through the day) - programming language you know- C/C++ for arduino IDE -do you have a arduino uno and a stepper motor?- Yes, regular stepper

Hi, my name is Zeeshan. I would love the opportunity to assist you in making this automated door lock system using Arduino and steppwr motor. I have read all of your description and make a simper and good design. I have completed BS Electrical Engineering and currently enrolled in MS Electrical Engineering. I have more than 3-years of experience in Arduino. If you want to know more about my skills or expertise, please feel free to message me. Thank you Best Regards Zeeshan Approach: 1) if you don't want to use IR sensor on door fram then we can adjust it somewhere else. 2) we can use current sensor so when there will be an obstacle, the induced current will increase which can be detected and hence door will be reopened. -Name: Muhammad Zeeshan -Country: Pakistan -How good is your english from 1 to 10 ( spoken and written) : 9 put of 10 -how meany hours a day can you work: I can work 4 hours a day. - programming language you know: Arduino, C++ -do you have a arduino uno and a stepper motor? Yes I have both of them. - if you have a stepper motor is it a regular stepper or a stepper with an encoder? It is a stepper motor with encoder.

Hi there,I'm an electronic engineer, And i'm quiet Experienced with High Speed PCB Design and Implementation. I'm an expert in Eagle CAD,and Circuit design and C,Java,PHP and arduino programming Can you please send me a message,So we can discuss more about the project? I can design your door closer with steppers, Perfectly and send you the files ready to manufacture Im chamli priyashan. from Srilanka English 8/10 I know C,Java,PHP and arduino I have a entire lab with all the equipment's,So this is really straightforward. I got only bipolar steppers without the encoder. Design is a huge part of my life and I work hard to produce the highest quality, effective, innovative, timeless, designs that my clients will love and I would love to work with you!! :) Thank you

-Name : Sherif Sameh Armanyous. -Country : Egypt. - English level : 9/10 - Up to 8 hours per day working. - C Programming language . - I have Arduino and stepper without encoder. We can chat to discuss your vision regarding this project and how is the solution can be implemented step by step till reaching your goal. I will use the following : - Arduino uno. - Stepper motor with encoder - motor driver. - Driving algorithm. There can be an algorithm deals with encoder to detect barrier in front of door, and stop motion. If you choose me, I think you won't regret. Best Regards,

-Name OMAR SEVILLA -Country MEXICO -How good is your english from 1 to 10 ( spoken and written) 8 -how meany hours a day can you work 4 to 6 - programming language you know ASM, #C and C++ -do you have a arduino uno and a stepper motor? I have an arduino uno (I don't have a stepper motor but I can get one easily) - if you have a stepper motor is it a regular stepper or a stepper with an encoder? I can get both versions and develop for any of them I have more than 4 years of experience developing hw and sw for embedded systems including arduino boards. I can suggest a measurement of the current in the motor to detect if there is an "obstacle (your hand)". This obstacle will provokes a increase of the current in the motor. This measurements must be performed constantly (polling strategy). This could be using an interruption or an RTOS (like FreeRTOS for Arduino) Anyway we can discuss more details in chat. I will glad to answer your questions about how we can do this project. Regards
