I would like to add a functionality to an already existing product. I only need the controller for an aquarium water pump to be able to change speeds at pre programed times. it would work along the lines that the speed would remain constant until the next time set came. Then the speed would adjust to that preset. This would continue on a 24 hr loop. I can provide a working copy of the already commercially available system I want to adapt.

Hi, I see that Aquarium water pump is made from DC motor, right? I will use PWM to change it's speed. But I need complete documentation of system. I need wiring diagram, and previous code that need to be modified, or even if you don't have all of that we can create one. My background is Electronic Engineering, and my main job is Electronic designer & Firmware programmer. For arduino, I know both of its firmware and hardware. I have use it since 2013 for various kind of project I did. Lets discuss the detail of this project over chat. Let me help you for this project. Best Regards, Rijal

Hi. Interesting project. I would like to know the model of the aquarium pump that you have. There are some that use a small DC 12 volt motor and others work with voltages of 110-220 volts AC. In either case it is feasible to do what you want, but of course the design varies a bit. I suggest using an arduino development card with some components. Please, provide a working copy of the already commercially available system you want to adapt to check it. If you have any questions or comments please do not hesitate to let me know. regards Darwin Pardo

I can provide you with a system design that will control your pump motor based on preset times and adjustable speeds. I can produce the design in AutoCAD and include the manufacturers technically data sheets for the equipment required to install the system. I have 19 years of experience in electrical engineering designing motor controls from fractional horsepower 24VDC to 5,000 horsepower 4,160VAC. I have completed large scale motor control projects for NASA, the Ohio State University Center of Automotive Research, the City of Louisville Kentucky, the Ohio Department of Transportation and many other private and public clients. I have completed several motor control projects within this past year and I am currently engaged in another. You can see examples of my work here in my project portfolio https://www.freelancer.com/u/ProjexConsultant Please contact me to further discuss the details of your project. I am available to start working immediately. Thank you for taking the time to review my bid and I look forward to working together.

We are a team of Engineers with experience with Arduino, we can make the timer and variable speed controller for the pump using the expertise we have. The pump is a DC pump? Hire the BEST forget the rest.

Please let me know the specs of the pump and details of the existing product. Kindly note that I'm open to this even at a lower price, because I've been on freelancer for more than a year but not a single bid is awarded to me so far. So what I primarily expect from this job is to get some positive feedback to build the profile.
