MQTT and API implementation using Python Paho-Mqtt

Install Required Libraries:
Make sure you have the required libraries installed. You'll need the paho-mqtt library for MQTT communication and the pyserial library to read data from the 3Dconnexion space mouse.

pip install paho-mqtt pyserial

Initialize MQTT Client:
Create a Python script to initialize an MQTT client and connect it to the MQTT broker.

import paho.mqtt.client as mqtt

mqtt_broker = "broker_address"
mqtt_port = 1883
mqtt_topic = "topic_name"

client = mqtt.Client()
client.connect(mqtt_broker, mqtt_port)

Read Data from 3Dconnexion Space Mouse:
Use the pyserial library to read data from the 3Dconnexion space mouse. The exact steps might vary depending on the specific model and protocol of the space mouse.

import serial

ser = serial.Serial('COMx', 115200)  # Replace 'COMx' with the correct serial port name and baud rate.

Format Data and Publish as JSON:
Read the X, Y, Z translations, and rotations from the space mouse, and format the data as a JSON document.

import json

while True:
    # Replace the following lines with the actual code to read data from the space mouse.
    x_translation = 0.0
    y_translation = 0.0
    z_translation = 0.0
    pitch = 0.0
    roll = 0.0
    yaw = 0.0

    data = {
        "Translation X": x_translation,
        "Translation Y": y_translation,
        "Translation Z": z_translation,
        "Pitch": pitch,
        "Roll": roll,
        "Yaw": yaw
    }

    json_data = json.dumps(data)

    client.publish(mqtt_topic, json_data)

Run the Script:
Run the Python script to start reading data from the 3Dconnexion space mouse and publishing it to the MQTT topic on the broker.
