Hey guys,

Im' havin trouble with figuring out how a servo works. I use this http://www.servocity.com/html/hsr-5498sg_servo.html whose pulse can range from 600us to 2400us.
The thing i dont understand is that if i want 600us, do I have to send a signal with period of 600us(ON->300us off->300us), or should I send signals of duration 2400us with 600us ON.

Thanx John
:(

Use 'rc servo' as search term here and on google. Get a coke. Start reading. The variable width pulse repeats 50 times a sec.

Neither. You send a pulse whose width is 600us at a frequency that the servo expects (typically 50Hz).
