 #### Methods
 
-- `led(r: int, g: int, b: int)`: Sets the LED color. Values should be integers between 0 and 255.
-- `move(right: int, left: int)`: Sets the motor speeds. Values should be integers between -100 and 100.
+- `led(red: int, green: int, blue: int, duration: int)`: Sets the LED color. Values should be integers between 0 and 255.
+- `move(left: int, right: int, duration: int)`: Sets the motor speeds. Values should be integers between -100 and 100.
 - `wait(duration: float)`: Adds a wait command with a given duration in seconds.
 - `run()`: Executes the commands in the order they were added.
