Python Tutorials – Lesson 5 – Sweep Servo Motor Control Using Raspberry Pi Pico

To test servo motor using Raspberry Pi Pico

Required Components

1. Servo motor (5V) _ 1 no
2. Raspberry Pi Pico board _ 1 no
3. Connecting wires _ 1 set

Circuit

Steps

1. Make sure the components are working properly.
2. Connect Raspberry Pi Pico board VBus and GND pin to the servo motor by using wires.
3. Connect servo motor data pin to the Raspberry Pi Pico pin GP15.
4. Check the Python program.
5. Check the circuit connections.
6. Run the Python program.

Python Program

from machine import Pin,PWM
import utime

MID = 1500000
MIN = 1000000
MAX = 2000000

led = Pin(25,Pin.OUT)
pwm = PWM(Pin(15))

pwm.freq(50)
pwm.duty_ns(MID)

while True:
    pwm.duty_ns(MIN)
    utime.sleep(1)
    pwm.duty_ns(MID)
    utime.sleep(1)
    pwm.duty_ns(MAX)
    utime.sleep(1)
