powerState abstract method
Returns whether or not the motor is currently powered, and the portion
of max power (between 0 and 1; 0 indicates that power is off). Stepper
motors report true
if they are being powered while holding a position,
as well as when they are turning themselves.
// Check whether the motor is currently powered and
// check the percentage of max power to the motor.
var powerState = await myMotor.powerState();
var powered = powerState.isOn;
var pct = powerState.powerPct;
For more information, see Motor component.
