Backyard Aquaponics
A place to discuss aquaponics

From what I can see that it is just a two wire motor and it should not have any problems.

I think its 5V for arduino's?

There are ways around it. The arduino usually doesn't have enough amps to run the bigger motors, even if they are 5v ones.

There are motor shields that you can attach to them, so external power goes into the motor, and the power going in is regulated through the arduino.

Sorry I ment with using the shield. I have used the motor shield several times form my projects.
3D Printed Mecanum Wheels

The shields are good up to .6A 24vdc motors on the version I have (Adafruit V1.2) but I have kept them under 6vdc. Never got steppers to work with the shield. They usually just buzzed or only moved one way. I was also using pulled steppers from printers and could not find info on them.

Wise advice

Thanks Brian.

That's the sort of shield that'll let you use external power, there are also stepper motors shields that do the same. I tried the steppers direct on the arduino, but it just sort of clicked. They are a microcontroller, aren't really designed for powering things like that.

It annoys me that folk develop a product and then start to invent names to make them sound better.. or different

"Shield"...

I shield something from Interference...

and I interface to a motor.. or I have a "Motor Driver"

I ordered a couple of these.. I like the idea of 3 to 24V so that you can completely control delivery, and I hope there will be lots of torque at ANY voltage..

What can you run directly from an arduino pin?

I think PICAXE is only enough to run an LED or a cell phone vibro-motor or similar. Twenty milliamps or something.


Also... was it you that owns an oxygen probe?

it's only a few lines of code and one extra pin (I think) to add another direction.

But my feeder is overkill if you dont want it to be a demand feeder.

Either way PICAXE or whatever, I'm sure someone (or me) will help you with the code.


There's probably a much simpler way to just dump a given amount of feed into two tanks in turn rather than programmable chips if all you want is a solution. ie rather than learning stuff. IT's been so long since I actually needed a solution, that sometimes I forget that people just want to get things dont rather than just endlessly learning.

Solutions that test the invention engine are free.

Just say EXACTLY what you want it to do, and I'll run it through the engine and see what it spits out.

You never know.
