Hi,

I have a little question: How will the input pin of the servo motor (normal, hobbyist servo) react when:

The motor is disconnected by the Si4435 transistor from the +5V net (a logic high is on its gate), AND there's a signal coming through the SIGNAL pin (TTL, 0-5V.). It should do nothing, but than again, if the servo had some weirdly connected protection diodes on the signal pin, it might drain a little current, possibly act strange. Will it?

Thanks,

David

There are pointy haired bald people.
Time flies when you have a bad prescaler selected.
