Servo

Servo motor — is a motor that can rotate to a specific set angle. Unlike a regular motor, it cannot spin freely (so you can’t make a fan or a car motor out of it), but with a microcontroller, you can precisely set the rotation angle of the servo drive with an accuracy of half a degree, and it will hold the set position.

Basic usage

---

Servo(pin) -> PWM

To create Servo object call Servo(pin).

Args:

• pin (int) - pin port (8, 9 or 12)

Returns: Return a output pibody.PWM for pin.

from pibody import Servo

servo = Servo(9)

---

.angle(val | None) -> None | int

Get or set the servo angle (0–180 degrees).

Args:

• val (float) - is optional which sets the angle (0–180 degrees)

Returns the current angle (0–180) when called with no argument, otherwise sets angle and returns None.

from pibody import Servo
from time import sleep

servo = Servo(8)

servo.angle(180)
sleep(1)

print(servo.angle())  # 180

servo.angle(90)
sleep(1)
servo.angle(0)
sleep(1)

print(servo.angle())  # 0

Other Functions

---

.freq(value | None) -> None | int

Args:

• value (int) - parameter value is optional which sets the frequency of PWM. By default value is 50

If value is empty, method returns frequency thats used before.

servo.freq(50)

print(servo.freq())  # 50

---

.duty_u16(value | None) -> None | int

Args:

• value (int) - parameter value is optional which sets the duty cycle of pibody.PWM. It can contains value in range [0, 65535]. By default value is 32768

If value is empty, method returns duty cycle thats used before.

servo.duty_u16(32768)

print(servo.duty_u16())  # 32768

---

.on()

Re-initialise the PWM output (enable the servo).

servo.on()

---

.off()

De-initialise the PWM output (disable the servo).

servo.off()
