How to wire an ESC to an arduino

Thanks in advance!

I use 4-in-1 and what you are doing is all good.

Did you calibrate the ESC at least on the channel you are using?

ESC EMAX BLHELI Flash needed?

Hey, I got BLHeli 25A connected to brushless motor , it looks it got bad since randomly it will stop rotatating the motor ( I got 2 so I swapped and the issue went to the other motor) I bought a new BLHeli to replace the bad one, isnt it plug n play ? it doesnt work, connected the same way as the old one. both controlled via same pin on arduino nano .. so one motor works and the other one doesnt its not code related but maybe someone here had that issue [25a.jpg] [25a.jpg]

Here

  Serial.println("loop");
  s.writeMicroseconds(1300);

just writing the same thing, are you expecting this to make the motor spin slowly? The ESC may itself need to see no throttle before it spins anything; it may need a more elaborate proof of being connected to something it makes sense to obey.

Then writing something like servo sweep does, within the pulse lengths you expect to do anything.

I see your propeller is off, I mention it out loud for anyone else reading. Remove the propellers at this point…

Since it's a BLHeli firmware, you can poke around in there with the BLHeli Configurator. I know you either have done, or will find it easy to do.

I've been getting through some packs lately, not flying any better but I am having fun and ppl who don't know better seem impressed. I hope you are having fun, I hope you are flying some of the time you are putting into this!
