I am currently using an Arrowind ESC and arduino to control a brushless motor. I have a 3 cell zippy lipo for the motor itself, and am using this code: http://arduino.cc/forum/index.php?PHPSESSID=ffd52316f6e5e60d8e7ffdec319ae4bc&topic=20594.msg151977#msg151977
However, I can only get the esc to beep, and it attempts to turn the motor for a second it seems but it does not move. It then beeps an error. What am I doing wrong? Thanks!
P.S.: I have it set up like this http://1.bp.blogspot.com/-eCJRq4AXT6g/TvtZzkNZdAI/AAAAAAAAALw/Pmk506CwbnY/s1600/schematic+Brushless+motor+ESC+LIPO+hexacopter+quadcopter+cuadricoptero+tutorial+how+to+aeromodelismo+helicoptero+RC.png, only to pin 9 instead of 8
Could you show us the code you are using?
I have seen a number of places mention that ‘some’ ESCs require a setup sequence to work properly.
Well, from my limited
Well, from my limited experience… controlling ESCs via arduino can be quite tricky… or very easy. That will depend mostly on the used ESC.
Take a read of what’s going on here: https://www.robotshop.com/letsmakerobots/node/35684
In summary I advise you to use the procedure/code that can be found here:
http://techvalleyprojects.blogspot.pt/2012/06/arduino-control-escmotor-tutorial.html
this way you can iteractively send servo angle values to the ESC and try to discern what the activation/arming values are. However, in the end I found that HobbyKing branded ESC I was using, did not like to conform with the arming procedure very much when I went on to do it programatically… it would be hit and miss (I suspect so timing issue). On the other hand I got great success with a Mystery 30A ESC… so much that in the end I’ve decided to just instead buy another one to replace the HobbyKing one.
