It depends how you want those 4 motors to be controlled. Speed? Direction? If all 4 motors need to be independently control with different speed, direction, then your controller will need to have 4 PWM and 4 DIR (digital output), and that is possible. As for the code, I believe is quite straight forward, just modify and look at the output, assign the pin according to the connection.
