Propeller directly controlling a Servo
![william chan](https://forums.parallax.com/uploads/userpics/RBTCEMRWP85K/nQFR9OII9OM33.jpg)
Hi,
I need to connect a Prop directly to a Parallax Standard Servo Motor.
1. Can a propeller pin (at 3.3v) directly (via 2k resistor) send pulses to a servo motor powered by 6volts.
Will the pulse voltage be high enough for the servo?
2. Will some stray current from the 6v source stray into the IO pin and kill the Prop?
3. If I disconnect only the negative wire of the servo motor from the ground,
will the control wire start to leak current?
Thanks.

2) Not supposed to happen. That said, things break and, in breaking, may damage other things. The 1K (or 2K) resistor should protect against that.
3) Maybe. It depends on the circuitry inside the servo.
