Hello,
Can i plug in an analog servo into one of the digital ports?
I ask because there are way more digital ports than analog ports.
I know an analog ir sensor and a ping sensor are for the analog ports only, right?
I want to buy analog servos cuz they are way cheaper, but there are only 9 analog ports.
Thanks.

So that leaves the digital ports to connect the servo's to.
The difference between an analog servo and a digital servo is not the connection method. The difference is the electrical internals.
An analog servo uses the pulses to "tweak" the servo position each time it receives a pulse. There are 40 pulses per second. Which means, with an analog servo you will get a bouncy twitchy response.
A digital servo "smooths" the pulses and uses a bit of prediction to determine where the servo is supposed to be. It really just continues to hold the last position until a new pulse width is returned.
You can read about servos on our tutoral section by clicking here
I ment that you can only select the 20 Digital I/O ports in ARC for controlling a servo. And not the 8 analog ports.
I'm sort of replying to:
"I ask because there are way more digital ports than analog ports."
and mr sures, i read all your posts, just making sure i dont buy a ton of the wrong servos...
local hobby people has a sale right now, foun a bunch of analog servos, micro and standard for 5 bucks, so im taking them.
thanks guys.
