View Full Version : PWM Command

Any comprehensive explanation about PWM command, especially when using this command to control DC motor via H-Bridge? And recommendation for Cycles value when driving two DC motors in open loop system, so both motor can spin smoothly with the same RPM?

ии Please see the BASIC Stamp Manual or the Help File within the BASIC Stamp Editor. The PWM command is not designed to run an H-Bridge, but to help the BASIC Stamps to generate an analog voltage through an RC filter. We carry a device for generating up to 4 channels of PWN which is suitable for driving an H-Bridge and can be found at the following link. I hope this helps. Take care.
