Merci pour la réponse
C 'est donc l'arduino qui gère la décharge..
Je vais donc mettre "Arduino Compatible Solar Charger shield -LiPo rider" a la place ...

Thanks for answer
It is the arduino wich control the discharge
I put "Arduino Compatible Solar Charger shield -LiPo rider" without control of lipo capacity

Hello, it a nice job
I am french so I beg your pardon for my poor English
Can you , please show me how the lipo and the solar cell are connected and how the arduino is powered by the little shield (Charger Board ) at the right of picture over the DHT ?
Thanks
