I'm an Arduino beginner. I've got 2 x 12V DC water pumps
plus 12V, 2A AC/DC adapter to feed them.
I would like to regulate the speed (flow) of the pumps programmatically by Arduino. My first idea was to use 2 channel Relay, however, it only supports two states - on/off. Then I discovered this DC Stepper Motor Driver:
That seems to be a good fit in terms of specifications, but I'm not sure whether it will work with the pumps? It makes me think of whether the DC Stepper Motor Driver may work with only specific motors?
Thanks for any advice!
