# NodeMCU_Lua
Ma petite caisse à outils pour le NodeMCU en Lua ;-)
## Ma petite caisse à outils pour le NodeMCU en Lua ;-)
J'y mets, pour l'instant tous mes petits projets en NodeMCU Lua afin de me faire une panoplie d'outils pour pouvoir utiliser très facilement les modules ESP8266.
J'essaie de les trier de manière logique, mais des fois ce n'est pas possible, donc il est bien de se laisser balader de temps en temps dans la structure de dossiers afin d'y trouver quelques perles ;-)
Et bien entendu, cette structure est vivante, donc elle peut changer au cours du temps !
## Ma petite documentation perso
Ma petite documentation pense bête où je mets pour l'instant pleins de choses que j'ai trouvées sur le NodeMCU ou ESP8266 en Lua
### NodeMCU ESP8286, mais c'est si simple ;-)
[https://docs.google.com/document/d/1q64uK3IMOgEDdKaIAttbYuFt4GuLQ06k3FLeyfCsWLg/edit?usp=sharing](https://docs.google.com/document/d/1q64uK3IMOgEDdKaIAttbYuFt4GuLQ06k3FLeyfCsWLg/edit?usp=sharing)
## La communauté Leman-IoT
Une communauté regroupant les utilisateurs de NodeMCU Lua et bien d'autres IoT s'est crée à Lausanne (Switzerland) !<br>
N'hésitez pas a y faire un petit tour et aussi a y participer car on est toujours plus fort à plusieurs ;-)<br>
[https://zuzu59.github.io/leman-iot/](https://zuzu59.github.io/leman-iot/)
zf181118.1016
Encore en bordel pour l'instant, mais j'y travail :-)
