  • 我是使用 YouTube 幻灯片制作程序 (https://www.youtube.com/upload) 制作此视频的



    Tous est dans le titre.

    - 1 Arduino Uno

    - 1 74HC595 pour multiplier les sorties de l’Arduino.
    Je pourrais me passer du 74HC595 vue les 7 sorties nécessaires pour l’afficheur.
    C’est en prévision d’un multiplexage de plusieurs afficheurs.

    - 1 ULN2803 (réseau de Darlington) pour alimenter les segments (entre 60mA et 80mA par segment, beaucoup trop pour un Arduino.). Peut être remplacé par 7 transistors NPN.

    Par contre je comprends pas pourquoi ca fonctionne car je n’alimente pas les LED.
    L’alimentation (+5V) vient de l’Arduino, il n’y a pas d’autre source d’alimentation.
    Il n’y a que les 3 fils (latch, clock et data) entre l’Arduino et le reste du circuit + une masse.

    Mystère….
