All these protocoles are analogique... i'd like to use DShot protocole for numerique, much more reliable, but not compatible
But you right, Oneshot125 looking already much more reliable than standard PWM, i'm gonna learn about it.
The arduino nano is in the command, in order to be as far as possible as the power source... The command is in a 3D plastic box for now, i'll probably made an aluminium one of prototype is OK... So conductive paint looking the easiest way for now.
Separate battery could be a good think, i'm gonna think about it.
Well, in case you want hightest EMI-related protection for the cable running through your command box and the motor, the solution is a little different.
What you need to have in mind that highest protection is given when all(!) is inside one box with conducting surface, that is:
All housings made of conductive material
All housings bonded to paraglider structure - at least their should be a conductive path between all electrical components. Keep resistance low (10mOhm).
Use harnesses with 360°-Shielding; you'll need dedicted backshell and EMI-sleeves for that.
Shielding has to be bonded on both(!) sides
... if you follow this, you'll see that virtually everything is in one shielded box. So no chance that external threads will have success. To connect a shielded cable only on one side to ground is fine for electrical field, but not for magnetical ones.
You may test without 360° shielding before for signal quality - its needed only in harsh environment or "powerful" pulses (of your signals). And, well, I guess to won't fly in vicinity of a thunderstorm ...
I hope you have already discovered this is NOT the right forum to ask for help. There are people claiming that they have vast experience but they are giving misleading or wrong advice. There may be someone who actually knows what you are trying to do and can give you good instructions - but it is very difficult to find the good advice in all the trash. You should try to find someone you know and trust to help you (or at least show them your plan). You don't know other paragliding people who have something similar you aim to do? Maybe buy/lend some professionally made electro-paraglide to look how it is done?
Your project is large, expensive and have a lot of possible problems. You should not rely on what say random people on low voltage, low power, low cost electronic toys forum for beginners. Maybe there is some paragliding forum where you could find someone who already did this?
That's an ESC which is not PWM. (per se). It's PPM , and you would need to use the Servo()
library, not a pwm output pin.
I've controlled ESCs with an arduino this way. It is no different than controlling an RC servo.
It is however, totally different than using analogWrite with a pwm output pin.
