Titre de la fiche expérience :

Description (résumé)

La station météo est une maquette qui permet à l'utilisateur d'obtenir les informations relatifs à la météo : la température et les conditions climatiques comme le soleil, la pluie, les orages, le brouillard la neige ou juste les nuages.

Elle utilise des leds et des planches en bois sur lesquelle sont gravées des pictogramme de météo (soleil, nuage, etc..) placé à coté des leds.

Matériel nécessaire

- 8 leds
- Des leds matricielles (minimum 7 en longueur par 5 en largeur) ou un écran led si possible 
- Des planches en bois (ou quelque chose de solide, découpable et gravable)
