arduino duemi with motor driver

[K_sQuare]

I have a arduino duemilanove and DC motor driver FD04A. I would like to use the arduino duemi to control 4 dc motors. Is it possible to control the FD04A driver from arduino duemi or I must use the arduino shield?

No.... you should not require additional shield, just correct wiring

Arduino have 6 PWMs, should be sufficient to drive any driver that need speed input

FD04A requires three input where else arduino only hav 2 output to drive a pwm for a single motor.

It seem you are not familiar with Arduino neither do the FD. I am not familiar with Arduino too, just started. Same to FD04A.

Anyway looking at the product page of FD04A, I notice it has 4 channels of motor driver, so you can actually control 4 motor independently, need 4 PWMs for that.

OK, about arduino, as far as I know, it have at least 6 PWM pin, use analogwrite() function to output PWM signal, you can refer to arduino site for that, analogWrite
