Arduino Acts weird when using servo libary?

Grumpy_Mike:

Does the HBridge actually need 4 PWM inputs ?

No but he has 4 H-bridges, so you need one PWM pin per bridge to control the speed.
You only need two pins per H-Bridge as you can wire any enable permanently high.

I only have on H-Bridge chip that is powering two DC motors.
The Enabels are not an issue. I need 4 PWM pins for 1A, 2A, 3A, and 4A.
With these four, the PING sensor, and the PING servo, I am now short 2 PWM outputs. I was woundering if there was a work around for this?
