I have been building a project, and I bought the QUICKRUN WP 880 dual brushed ESC and I have tried everything to integrate it with Arduino, but nothing has worked.
Can you please help?
If you've you've tried everything, and nothing has worked, then clearly it can't be done.
If you've tried everything you will have tried the Servo library, and programmed the correct arming sequence?
My advice with any ESC is use a servo tester manually first to see how to arm it and check the behaviour.
Servo testers are cheap and useful.
