  DC motors vs. servo motors
 
The nature of the PWM (pulse width modulation) is entirely different for servo's vs. plain DC motors. For a DC motor, it has a two wire connection. All drive power is supplied over these two wires -- think of a light bulb. When you turn on a DC (...) (26 years ago, 6-Jun-98, to lugnet.robotics.handyboard)
 
  Re: motors
 
For servo, there is a certain threshold duty cycle (say 50%) of the PWM signal, where anything above this threshold will make it to run forward, and less will make it to run backward. So, you still need to apply the PWM even if the servo is not (...) (26 years ago, 6-Jun-98, to lugnet.robotics.handyboard)
 
  Re: LCD Removal
 
Hello, Does anyone know if the Rug Warior Pcode run without the LCD? (Pcoderwl.S19) If not : 1 is there another RW pcode that will run without the LCD? I using the RW pcode on my Fingerboard II with out the LCD and I think this may be an issue. (...) (26 years ago, 6-Jun-98, to lugnet.robotics.handyboard)
 
  motors
 
That did answer my question. I am not familiar with servo motors, I have only used plain DC motors. I am also familiar with PWM. I was just unable to determine if the same PWM signal that drives plain DC motors could also drive servo motors. From (...) (26 years ago, 5-Jun-98, to lugnet.robotics.handyboard)
 
  Re: LCD Removal
 
it's easy: just use the replacement pcode_hb.s19 file provided by Kent Farnsworth: (URL) your message you said: (...) and still have the HB work. My design does not require the LCD, so if i could r emove it my robot would then be a little more (...) (26 years ago, 5-Jun-98, to lugnet.robotics.handyboard)
