DC motors can be controlled by the L298N DC motor driver IC, which is connected to your microcontroller.
L298Ns can control up to 2 DC motors. You can easily add motors through the program code.
You can set DC motor speed by changing the duty-cycle of each PWM signal.
The PWM is a square-wave signal which has two parameters: frequency and duty-cycle.
If a PWM signal's duty-cycle is 100% than the motor spins with maximum rpm.
In case of 0% the motor will stop. Motor speed and direction in your Ozeki software can be changed
on each motor with the motor's own adjustable slide bar from -100% to 100%.
If the slide crosses 0 than the motor will change spin direction.
