bonjour
je recherche un specialiste ou une personne vraiment doué en language circuitpython
avec le logiciel MU
j utilise circuit python avec la carte adafruit circuit playground blufruit
y a t il une personne qui voudrait m aider a ecrire un code pour allumer des leds reactive au son.
je suis deja sur un forum adafruit mais c est compliqué je parle pas bien anglais
merci pour vos reponses
y a t il une personne experimenté ici qui connait le logiciel Mu, circuit python et
qui pourrait m aider avec circuit playground blufruit pour faire un code?

Bonjour,

alors effectivement si tu ne parles pas bien anglais c'est toujours plus compliqué.

Le fait de ne pas bien parlé anglais ne t'empêche pas de fournir un bout de code pour que l'on voit que tu as cherché à faire quelque chose, sans quoi les gens passeront devant ton problème sans y prêter attention.

merci pour la reponse

voici le code programme qui fonctionne avec une app bluefruit sur apple

j aimerais avoir aussi les leds interne a la carte qui seraient en reaction avec le son avec la carte circuit playground bluefruit
ce code ci dessous ne fonctionne qu avec 10 led externe, alors que je voudrais connecter un badeau led de 200 led au moins
et pouvoir augmenter la sensibiliter du micro au maximum

voila en fait il faudrait par miracle arriver a inclure dans ce code un autre code pour que les leds externe soit au nombre de 200 voir plus si possible
et surtout que la carte circuit playground bluefruit ou il y a dessus 10 led puisse aussi reagir avec le son
exemple de code pour la carte interne du circuit playground bluefruit
https://core-electronics.com.au/tuto...-tutorial.html
voici le code qui fait marcher a merveille les 10 led sur la carte circuit playground express qui marche avec ma carte bluefruit
mais il manque le code pour les leds externe celui donner plus haut
voici le code de la video 10 led interne
