On se propose de réaliser un système IoT à base de microcontrôleur ESP32 
qui permet de récupérer l’adresse Ip du système 
et d'afficher "ip", "region" et le pays relatif à l'adresse Ip du système sur 
un écran LCD 20X4 et mettre le broker à jour


Vous pouvez utiliser les api suivants:
1. http://api.ipify.org/?format=json
permet de retouner mon adresse ip public

2.	http://ipinfo.io/MYPUBLICIPADRESSE/geo 

(verifier sur votre navigateur le format de reponse du serveur)



parametre de broker :
server: ds-lce3-2023.japaneast.cloudapp.azure.com
port:1883
username:student
password:lce3
clientID: <Your Name>
topic:ds/location
FORMAT  Json File: {"nom_prenom":"kamel echaieb" ,"location":{"ip":"4.227.141.167","region":"Virginia","pays":"US"}}
