I try to build a motor control unit using Arduino.
The motor that I have to control is rated 4 to 6V, as described here : TKD 2CP-2511/4CP-2511 MC Motorised volume control | HIFICollective
I have 2 available Arduino DC motor control shields, but they are supposed to drive DC motor accepting 7V-12V for the first shield and 4.5V-12V for the second available shield.
My question is that I do not understand if it is (and HOW) possible to define the shield output voltage ??? in order to apply the appropriate voltage to the DC motor.
I have read the specs of the 2 shields and I do not see how to define the shield voltage output...
Can anybody help me ?
The available shields that I have are:
