Script de participation au défi Force/Python du concours TI-Planète-Casio de rentrée 2018 : https://tiplanet.org/forum/viewtopic.php?p=235402

30 potentiomètres poussables de 0 à 1 permettent de contrôler 252 lampes. Allumes-en un max tout en en grillant et gaspillant le moins possible !

Appel : pot(k,v) avec : k, le numéro de potentiomètre de 0 a 29; v, sa valeur à régler de 0 à 1

Bonne chance !
