I have an Arduino Uno with a WiFly shield. I want to use 5 PWM ports on the Arduino to control motors, but some of the PWM ports are used by the WiFly. Looking into it I think I need to use the SPI bus but I'm not sure if this is possible with the WiFly shield or how to go about it.
I'm not sure how I'm supposed to wire the motors so that they can work alongside the WiFly.
If you could point me to a tutorial (I haven't been able to find one similar enough to my case to understand) or if you could give me some pointers, that would be great.
