expanding arduino pwm pins

Projects General Guidance

Hello!

I'd like to expand arduino mega pwm pins for controlling DC motor. (with H-Bridge)

I have to control over 20 DC motors however I could not find the solution for this.

I found out that there is a TLC 5940 to control LEDs. Can I use it for controlling DC motor too?

OR, Is there any solution that I can solve it...?

PWM speed control only makes sense with rpm feedback and a (PID...) algorithm. I'd use multiple smaller Arduinos for these tasks, up to as many motors as the board supports.
