I recently bought a Torxis i01856 servo motor. Instead of having 3 wires, it has 4. I connected red and black to power source positive and negative, respectively. And connected white to a connection to pin 9 on an Arduino microcontroller, which is capable of pwm. Green I connected to ground on the Arduino. When I try using pwm at both 1500us and later at 2500us, nothing happens with the servo motor at any point (i.e. it doesn’t move). I don’t know if normally it would make some noise or not, when connected to power when a signal isn’t being passed, but it doesn’t seem to make any noise at any point. Would you be able to help me determine how it should be wired to control with an Arduino? So far most of the examples I’ve found for servo motors has been for 3 wire servos, so I’m not yet sure what I’m doing wrong for a 4 wire servo. Thanks.
]Did you connect the Power supply GND to your Arduino GND ? /:m]
]Could you provide a wiring diagram or a clear photo showing your wiring ?/:m]
]Could you also provide the Arduino code you are using ?/:m]
]Is your power supply 12V ? and can it supply a minimum of 3Amps continuously ?/:m]
