Hi guys. I'm new to Arduino, so please excuse if the answer to this question should be obvious... I am trying to run an RC servo with the "sweep" sample code from this page: https://docs.arduino.cc/learn/electronics/servo-motors/ My problem is that the servo does not make any steps below 9°. So wh…

If You post the code according to How to get the best out of this forum - Using Arduino / Project Guidance - Arduino Forum You will more likely get answers.

Ok, thanks for this hint. I checked it and added the Arduino board (and motor shield) version that I use. I didn't find a category/topic where my question would fit in better and I provided the code (in the link) and the wiring situation is described (I also clarified this more). Is there anything…

You should also try the sweep example that is installed with the IDE. Still waiting to see your code. It's important you post exactly the code that relates to the problem you're describing. Too many times, "but I didn't change anything...important" becomes "well, just that, but that couldn't be t…

That's the same sample than the one I used. This code makes my servo move in 9° (or similar) steps.

How are you measuring the change?

The change of the servo position? I just look at the lever... The 9° "quess" comes from the fact that when I set the "pos" value to 8, nothing happens and when I set it to 9 the servo moves. So the "critical" value is somewhere between 8 and 9.

Interesting. Thought you might be measuring change in pulse width, which runs IIRC around 6 us/degree. Sorry, can't help until I get to the lab, won't be tonight. Maybe, others?

Are you sure you have a 180 degree servo, not a sailwinch or continuous type. Which servo, and how exactly are you powering it. What motor board. Leo..

The servo (one of the two I tried) is this one: DS125MG Digital Metal Gear Servo 10mm 7Kgf.cm 0.12sec for Glider Wing – KST-Servo I limited the total travel angle to remain in the field that the servo can handle. See code below. Now the servo makes the travel in four steps (of approx 9°) and then t…

Please add new information in a reply, not in the original post. It makes the conversation look confusing.

Please post code here, not via links. Many helpers can't pick that up. Reading the code here might be the only option.

Failing to use D5 D6 & D9 pins to control ESC/Motor, only works with D10
