    Hi luni,

    Great. Thank you. That adafruit breakout board might be the way to go. I'll study up on it.
  4. Best way to expand the number of Digital Outputs on Teensy 3.6

    Hi,

    I am planning on making a Midi Controller that uses a Teensy 3.6. I will be using a lot of Analog inputs and Digital inputs.
    I also have a lot of RGB Leds, with each color, Red, Green and...

    @defragster Ok got it. thanks. I will try and grab it from the Vin pin and see how that goes.
  6. powering a LED display with 5v using a Teensy 3.6

    Hi,

    I have two of these LED displays that I want to connect to a Teensy 3.6 and power. They require 5v

    Hi Kirazvora,

    I learned from someone else on this forum that it's good to put a small capacitor between the power and ground. As a matter of fact, for midi controllers, if you have a potentiometer...

    Fastest Analog Midi Input possible?

    Hi,

    I made a midi controller with a Teensy 3.6. It's pretty cool and it totally works. However, in able to play it like a real instrument I want it to read analog data as fast as possible.

    Sending and Receiving with usbMIDI.read

    I am attempting to make a midi controller with 14 analog inputs and 11 digital outputs (LEDs).

    In my void loop() I need usbMIDI.read(MIDIchannel); because I only want to receive midi...

    oddson, Oh yeah you are right. If the message is not on the specified midi channel, then it's not read. Thanks for the observation.

    Blackaddr, thank you for your response and feedback.

    I tested the code and it seems super fast and responsive. I'll try and implement some of your suggestions and see if I can simplify this.

  23. Using USB Midi Control Change info to control a LEDs

    I tried it without aref and it was way more unstable, so aref helps a lot. I just figured I should use it since I've used it previously in my Arduino projects.

    Ok here are some images.

    It might be hard to see what's going on so I'll explain it as well. Aref is connected to 3.3V. Coming out of each sensor is a power, ground and signal. Except for the...

    Oddson thanks for your help.
