controlling servo speed is really crude system i think. Your codes might change according to your servo type.
I did some projects about sg90 servo speed. I used for loop to change degree and i added delay in loop.
for example,
for(int x = 0; x<=180; x++) {
servo.write(x);
delay(100);
}
if you increase delay, your servo will turn slowly but low res.
some servos can move slowly by decreasing vcc voltage
seems like you didnt get what i want. i cant translate your example to my problem. i dont want the servo to move by itself. i want to control the angle with a slider and it should move slow all the time. help would be much apprechiated
hi, do you think something like this could work? (still not working properly)
regards
