You mean to center the servo while modifying it?


No you do not need to change the circuit - but you do need to change the program!   :D

Related question:
I was modifying my servo's and I was successful, i think.
When was adjusting the pot, rotation didnt stop until the pot was maxed out far clockwise. Also, it wasnt all that sensitive, like it says in the tutorial. I searched around, and there are tons of articles on modifying servo's but no one references roughly the position of the pot when the gear stops turning.

Did you give it the correct pulse to make it go to center?

Also, make sure your program is set to your oscillator frequency

For example a pulse of 150 @ 4mhz MCU  would be a pulse of 300 on a 8mhz MCU
