razvanc_roro:
I'm a novice in programming the microcontroller and I found out that the servos are being modified by this... How do I send the signal to sorvo to make 0 degrees on the gears?
Also I want to ask you if I could make this after building the whole robot and turning it on.

Thank you!

hazzer123:
It depends which microcontroller.

You will need to make a delay of about 500 uS.

Then you turn on the signal pin for the servo --> call the delay --> turn off the signal pin

Repeat this a couple of dozen times a second.

For different angles, you could great a 8uS delay and loop it a number of times. This would be added onto the 500uS delay.

Using 8uS means you have the range of 0.5 - 2.5 mS in 256 steps.

 or use 35 cpu cycles. 20-50 control angle.

hazzer123:
Won't the length of the cpu cycle differ between microcontrollers?

ed1380:
if you use the same mcu it won't
