Need help with project PWM with DC motor control

SChid

Hey Guys,

I have a project in which I have a DC motor (a winch that has a tether which is supposed to control the direction and velocity of a blimp) that needs directional and velocity control....I have a BS2p40 board with a PWM...and need help with the coding for this...seeing how I am relatively new to the PBASIC language.....has anybody done anything like this...and if so can you please give me some sample code to learn from....because I am lost...thanks...

Hello,

The PWM command on the BASIC Stamps isn’t really geared toward motor control. It’s designed to generate an analog voltage using a filter circuit. If you need direction and speed control for a motor I would use a dedicated motor control. Do you already have an H-Bridge? If not how are you driving the motors?
