Basically, I want to use PWM wave or something alike from Arduino to directly control the speed of a brushless motor through an ESC.
I saw an example on the Arduino Brushless Motor Control Tutorial | ESC | BLDC by Dejan . However, I saw some other people mention about flash ESC such as Flash ESCs with ANY Arduino!
But I was confused about why they needed to flash the ESC? Can I just control the speed of the motor by sending PWM wave to ESC directly from arduino? I wanted to use BLHeli ESC.
