In this video I show how to program the real 360° Gray GeekServo.

OH you didn't get a single comment yet? :O Need to say thank you!

Recently got myself a Arduino BLE Sense V2 to see if the onboard gyro is usable to maybe do some funny things together with lego.

This is an excellent choice! I also use an Arduino Nano. . .
The combination of Lego, Arduino and RC servo will allow you to move forward very quickly in all your projects. I would even say that sometimes you have to know how to stop and think.
Currently, I am working on a large quadruped with servos that have a torque of 40kg.cm. I have a lot of breakages and I think I'm at the limit of what is possible with Lego. And yet, I advance.

More modestly, I ordered the latest Uno, the Uno R4 WiFi.
I have already started to solve some interface problems to avoid any use of soldering iron and make the creation as simple as possible, even for children who are beginners.

Thank you for your attention. Don't hesitate to ask questions, here, or on my YouTube channel.

Great project of yours, had watched some of the videos, also the latest TRR and its funny and impressive!

Will ask questions if I got any - thanks! My hopes are that I can solve most of my future issues on my own as I am an IT systems engineer.. so should work out (excepts electronics maybe.. weak field yet :D).

I have already spoked with Oracid, about Geekservo programming in arduino. I just wanted to ask another thing and also bring this topic to a wider audience. So If I understand correctly we can program certain Geekservo, thanks to this arduino setup and then bring modified code in geekservo memory and apply new settings for example in RC setup (transmitter, receiver, ESC and rest of the family :D), right?

It would be great but unfortunately this is not. As far as I know, a GeekServo has no memory.

Oh, that's not good. I will need then start digging into my issue once again. One more thing, Oracid, do you think that maybe instead of 5 volts, putting 6 volts per µs can make a difference in physical rotation. So let's just get an example that you programmed in arduino a script like yours in a video and instead of trying executing it using 5 volts, you would use 6. Would that make a difference?

My knowledge of Radio Control is very limited, but it seems to me that it is not impossible that an RC transmitter can send the parameters of the operating range to a servo.
Maybe someone here could tell us more.

The allowed voltage is from 4.8V to 6V. Personally, I use it in 2S (7.4V/8.5V), but it is at my own risk.
A higher voltage increases the torque, nothing else.

And between those two batteries (7.4V and 8.5V) you see no difference in terms of rotation, just torque goes up, correct?
If that is the case, I am running out of ideas why my setup isn't working rotating 180 degree(90left/90right), but around 150-160 degree. Anyway, thank you Oracid for your knowledge. I will continue digging.

For @Krxlion. This morning, I have tested a Gray GeekServo with a FlySky FS-i6X transmitter and a FS-iA10B receiver. The servo has a 180° travel.

Note: A 2S battery has a nominal voltage of 7.4V, but when fully charged, it reaches 8.5V.

Thanks for the note, I didn't know about that battery behavior, cool to know.
Regarding your radio controller, I would prefer having "pistol-type" transmitter. I am also trying to figure out if providing different current (for example 3A), may have a visible effect on the range of rotation.

I have found what's wrong with my setup. I will share it here, although a scenario like I had is rather unusual. So basically the gyro function in X6FG receiver I have, trim the movement of geekservo. It I believe needs to do that in order to have some "movement range" to counter-steer. That's pretty much it, I have turned gyro function off, and I got proper 180 degree movement (even more). I wonder if a different receiver, and/or transmitter, could have done the trick to have 180-degree angle movement and gyro function, but that's for another day. Sorry If I flooded your topic with an unnecessary dose of information.
