How to Feeding power on arduino uno, using opto esc

now i'm make the drone with Arduino Uno

but I don't know how to feeding power on arduino board using opto esc.

I'm insert the 1st esc cable's white line on pwm 3rd pin and connect battery

but not feeding power.

what's the problem?

An ESC does not work on PWM. Use the Servo library to send to the ESC servo signals (which are different from PWM). You can use any digital pin to control the ESC.

ESCs often need to go through an arming sequence before they will work. Consult the data sheet for your ESC to see if an arming sequence is required and how to perform the arming sequence.
