![]() It occupies only two! pins of the Arduion board. This is a digital data connection between the Arduino and the Servo Shield. A pleasant side effect is that you do not occupy valuable channels of the Arduino for each servo motor. An external power supply is required for this. The Adafruit Robot Servo can control up to 16 servomotors simultaneously. It is a, on the Arduino attachable, extension of the Arduino. If you want to use more than one servo motor, I recommend using a servo shield like the Adafruit Robot Shield. Control many servo motors with ArduinoĪ servo motor needs a lot of power for the movements. Importantly, the command myservo.write (val) sets the servomotor in a specific position between 0 and 180 degrees. Of course, this is just an example to explain how it works. In this example, the servo motor is controlled to a position determined by the potentiometer at the analog pin 2. The program is the Knob example from the Arduino software ( File> Examples> Servo> Knob). Furthermore, a potentiometer is connected to the analog pin 2. The example shows, a standard servomotor connected to the GND, 5V + and digital pin 9. An incorrect connection can lead to damage here. A look at the description of the servo motor is always appropriate to make sure that it is properly connected. ![]() Common combinations are brown-red-orange (GND, plus, data) or black-red-yellow (GND, plus, data). ![]() Illustration made with Fritzing.ĭepending on the manufacturer, the cable colors may differ. These are two supply lines (plus and GND) and one data line. The servo motor is connected via a three-pole cable. All components are housed in a robust housing. A servo consists of a motor control unit (1), an electric motor (2), a gearbox (3) and a potentiometer for position determination (4). ![]()
