Hi,
I want to buy this peristaltic liquid pump with silicone tubing (https://www.adafruit.com/product/1150) and Adafruit Feather 32u4 Basic Proto (https://www.adafruit.com/product/2771). Do I still need to buy other parts to run this pump?
I found that there are two types of peristaltic pump, 5 to 6V and 12V DC power. Can someone let me know the difference between them? How to change the flow rate of this pump, and is it possible to reach about 10 mL/min?
Looking forward to your kind reply. Thank you.

Re: Peristaltic Liquid Pump and setup
Good Afternoon:
Sorry to post my question here. I was unable to locate where to post a new question.
Can you please provide information on the applicable viscosity range of the pumping fluid that can be pumped using the Ada-Fruit Peristaltic Pumps (12V DC or 6V DC). Are there any limitations on the recommended pumping fluid characteristics for these pumps? Thank you.

Re: Peristaltic Liquid Pump and setup
@Kading - You will need either a transistor or motor driver board to power the pump. It is not possible to drive it directly from a microcontroller pin.

To change the flow rate, you can change the speed of the motor. This code has an example of how to do that: https://learn.adafruit.com/adafruit-ard ... duino-code
Peristaltic pumps in general are not especially good at precise flow control. And those powered by DC motors are difficult to control at lower speeds/flow-rates. To achieve a low flow-rate such as 10mL/min you will probably need to pump in increments and go for an average flow-rate.
The 12v motor will probably allow for somewhat better low-speed control than the 6v.

Re: Peristaltic Liquid Pump and setup
@pipeengineer - We do not have any specifications on fluid viscosities that these pumps are capable of pumping.
