hi guys, This is my first time using arduino and I want to control my ESC using my Uno. I've tried to google how to controlling SEAKING ESC 120A, but none of them work for me. I use servo library, and I connect the GND wire to GND on uno, then Data wire to PWM pin (9). I've tried so many codes from the internet, the codes just send some various servo degree to ESC. But the ESC just beeping rapidly. Could u please help me?
Post your code. Usually the ESC needs arming before it works and this usually involves doing the servo library equivalent of setting the throttle to off before powering the ESC.
Google info about arming an ESC using an Arduino and you should find more information.
The easiest way to figure out how to arm a particular ESC is to play with it using one of these:
Then go and emulate the seqeunce in software. You can snoop in on the servo signal with
pulseIn() to measure actual pulse widths even.
