Hi mr ELECTRONOOBS
Want to ask about (ESC with Arduino) project.
As I understand we change the speed of rotation by potentiomentor. This potentiomet analog signal converted to delay time. (please tell if it is right)
But . As I can see each phase connected to PWM pin.How do we manage PWM duty ratio?
I mean in other projects I saw some current sensor.
If the DC motor works without load - PWM duty ratio is low. But the speed is high.
If dc motor works under load PWM duty ratio is high, and the speed is also high.
By this way I think we can save some battery power if the load is changeble.
What do You think aout this ?
