I have to drive a roller with the help of a motor. The speed of the motor must not be greater than 7 rpm as this is the requirement.
The next requirement is that I should be able to control the speed of the motor for each of my experiment which, I know, can be controlled with the help of an appropriate Arduino board and respective programs.
As I am new to the electronics background, I do not know which board should I make use of? and which motor should I use, DC motor or a stepper motor? I need a continuous motion.
Kindly help me with this.
