i have this esc turnigy 10A plush . i am given to understand that an esc has to be armed before giving it a pwm pulse. whenever i connect the esc to the pwm pin ,i get the 123 tone indicating battery is all right. After this it starts giving a single beep every 2 seconds . what am i supposed to do , plz help
Read the datasheet on how to arm it. Replicate the arming sequence in your code. If you need more help, post a link to the datasheet.
I think the usual process is to use the servo library and treat the ESC as if it were a servo like RC equipment does.
