# Servo-motor-control-in-Ardunio-using-HandCascade-tutorial-file-in-Opencv
It is the Servo motor control project of our Computer Vision work with Opencv. In this project, an Ardunio Serial port-based servo motor control project was implemented using Opencv and Cvzone artificial intelligence libraries. Below I tried to explain the details of the project step by step.
## Download Library
First, we will download the libraries we will use.
```Python
import cv2
from cvzone.HandTrackingModule import HandDetector
import numpy as np
import pyfirmata
import random
```
### Code block that we connect to Arduino
```Python
port = "COM5"
board = pyfirmata.Arduino(port)
servo_pinX = board.get_pin('d:5:s') #pin 5 Arduino
servo_pinY = board.get_pin('d:6:s') #pin 6 Arduino
```
We add the StandardFirmata project from the Arduino sample Firmata library. It is the library that allows Arduino to communicate with python.
