I have two servos for my robot and I read that I must calibrate them because it is very difficult to have the same speed both!
So I give them maximum values (500, 1000) and I see for example that the right servo is faster so I reduce its value until it goes straight.
The problem is that while I test the new settings it starts to turn to the opposite way (eg the left servo is faster).
I also made a programm that it turn the wheel only one time. I made a mark and I found the time it needs for the turn. But testing the same settings again and again I found that it is not accurate. Sometimes it was exactly on the spot and other was before or after the spot.
I wonder if this is normal. If it is not what could possibly wrong? The voltage is 5.59 (4*1.5V).
It is my first time I am working with servos
