Servo. Servo.write(90) // Turn SG90 servo back to 90 degrees (center position) Servo.write(45) // Turn SG90 servo Left to 45 degrees control the servo's direction and the position of the motor For potentiometer you can use anything value between 1k to 500k.Subscribe To. Int servoAngle = 0 // servo position in degrees Learn how to control position of Servo motor using potentiometer with Arduino. #include servo.h //add '' before and after servo.h Take a look inside of the SG90 micro servo SG90 is cheap enough to throw away when they break. Well, there are other high-end servos with a bit more muscle than the SG90 servo, but these high-end servos canât beat the price of the SG90 servo. All these specifications are really impressive for this little plastic box. At 4.8V, the speed of the servo is 0.12 sec/60°. You need torque to control the position of an object, for example, and this little box that weight 0.32 oz (9.0 g) can provide at 4.8V a torque of 25.0 oz-in (1.80 kg-cm). The motor shield simply brings out the PWM output lines from Arduino pins 9 and 10 to two 3-pin headers so that its easy to plug in and go. They have a 3-pin 0.1' female header connection with +5V, ground and signal inputs. Letâs make a short overview of the SG90 specifications. Step 1: Tutorial Hobby servos are the easiest way to get going with motor control. Even itâs cheap, less than $5, donât try to rotate the servo motor by hand because this may damage the motor. The Tower Pro SG90 servo is one of the cheapest servo motors that you can find on the market. Hereâs the circuit diagram for this example.
