From the project

Ensemble de systèmes pour l'arrosage du jardin

Jarduino2 est une évolution du premier jarduino fabriqué en 2019.

Le premier jarduino était construit avec des platines de prototypage et un arduino MKR Zero Wifi.

Ce nouveau jarduino est construit à partir d'un Nano. On peut le configurer à l'aide d'une interface MODBUS sur l'USB ou bien sur le port série d'extension. Il est possible de lui ajouter une extension Wifi pour le relier au réseau.
