    Using APA102 Midi controlled LEDs with Teensy

    Hi everyone,

    I'm currently working on a project implying MIDI and a APA102 led strip.
    As I'm quite new with Teensy in general, I'm wondering how to connect the APA102 LED strip to the Teensy ?
    I've been searching for a while but I don't see any clear explanation on how to connect the strip to the Teensy :/

    Any help would be gladly appreciated Thanks a lot !

    Use this guide

    For long strips must be use a 5V external source

    In teensy 3.5, wiring directly
    In the teensy 3.6 or any MCU with logic of 3.3 V, use a logic level shifter to boost 3V logic to 5V; something like a 74AHCT125
