PWM input

Hi All,
This is my first visit and I'm very excited about the possibilities.

However, before I buy a board, probably a Uno, a quick question.

For the project I'm planning I will need 4 PWM inputs and 4 PWM outputs.
Can the PWM pins of a Uno board do this?
Or maybe there's an expansion board available that would be suitable?

Best regards to everyone.

Hi Ron,
I'm pretty sure that all Arduino's have PWM, though, like you I am a relative newbie, so I may be wrong ;).

The Arduino Uno only has 6 PWM pins which is not enough for you, so you would probably want to go for the Mega.

Hope That Helped!

Thanks Koop.

I'll take a closer look at the Mega, though all these boards are a bit confusing to start with.

Thanks again.

Hi Richard,

I'm looking at making a quad UAV - quad copter - so I need to take inputs from the RC receiver servo outputs and read them, or modify them according to other parameters, like gyros, gps, etc.
Then output the resulting modified PWM to the motor speed controllers.
