But my design plan for the robot has one specific objective, I want to be able to easily control the speed and turning of the robot so I think that not having to worry about PWM in using a Motor is an advantage.
or just use delays ^-<
What are your opinions?
[...] but they need 2 i/o pins each.
Hi,Quote from: blackbeard on August 16, 2009, 12:25:26 PM[...] but they need 2 i/o pins each.That depends on the controller, motors can be controlled with a single pin as well.
yeah, generally two, but you can get circuitry like that found in servos on its own which would only take up one pin.
I've read some tutorial about a futabu servo and found that they require a PWM period of 20ms (or some other number). If the period that they require is constant, doesn't that mean that you can't control the speed of the servo? What about the direction then?
But the tutorial i read really did not mention how to change speed. But are you implying that the closer I get to 1 ms, the faster I get? and the closer to 1.5 the slower I get?And all that is after hacking the servo right?
