• Attention, capteurs en 3.3V SEULEMENT
• Attention, pas de hot-plug sinon risque de crash du raspberry pi
• howto I2C : https://www.pobot.org/Tutoriel-complet-sur-I2C.html

Pour installer :

sudo apt install python-pip python3-pip
curl -sL https://github.com/Seeed-Studio/grove.py/raw/master/install.sh | sudo bash -s -

On doit avoir à la fin :

  Lastest Grove.py from github install complete   !!!!!
