Re: How do I control 16 motors independently?

Thank you for your reply Doug. Yea there are a lot of variables to consider which seem to constantly change my requirements. The stepper/syringe pump will be the most consistent and accurate method I'm sure, but not really suitable for the type of dispenser I'm looking to build as it requires a lot ...

Re: How do I control 16 motors independently?

Thanks Joan! Apologies for my indecisiveness of the original requirements.
I agree, I think a stepper motor will work out more consistent than the peristaltic pump - so I'll look into this a little more.

Re: How do I control 16 motors independently?

Thank you Ravenous!
I'll keep thinking of the best way to get this setup to work as accurately as I can and as simple as possible too.

Re: How do I control 16 motors independently?

Thanks Texy. Yep, ignore the added ability of rotating in the opposite direction. It was just an idea I had for automatically refilling the reservoir with the contents in the tube. Just call me 'The Overcomplicator'. A DC Motor to drive a peristaltic pump sounds like it could be very innaccurate the...

Re: How do I control 16 motors independently?

Just an update... I have found something which looks absolutely perfect for my needs: Adafruit 16-Channel PWM / Servo HAT The only problem here is most of the peristaltic pumps I've seen are all DC motors and not these 3 wire servo motors that are required for this motor driver board. Do you think i...

Re: How do I control 16 motors independently?

Thanks Texy, I'll get a small prototype working so I can get a feel for it! Designing a PCB shield :shock: I'd be way out of my depth. I've seen some of examples of people designing their own, but I would not know where to begin in all honesty. I'd appreciate any guidance you can give on the subject...

Re: How do I control 16 motors independently?

First, get one motor working... Yep thats probably the best idea! :) I'll post a picture here when I've got the one one motor working. I plan to setup something using what Texy advised for starters: 1 x Rasberry Pi 2 1 x ULN2003 driver chip 1 x PSU for externally powering the single motor/pump. 1 x...

Re: How do I control 16 motors independently?

Thanks Texy - that's good information for me to get me started.
I'll look at getting some parts together and see how I get on.

How do I control 16 motors independently?

Hi everyone, I've been a software developer for over 11 years but building circuits has always scared me. I had a good idea recently for an automation system which I'm looking to setup, but need a little guidance on the type of hardware I need in order to setup a complete circuit which will allow me...
