MQTT and API implementation using Python Paho-Mqtt

Question

Hi Team I need some help on this requirement the program must write it using python. software written that gets X Y Z translations and rotations from a 3D connexion space mouse and publishes the data to a MQTT topic on a specific broker. The data must be formatted as a JSON document with keys for Translation X  Translation Y Translation Z Pitch Roll Yaw .

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.
