    [queued] LED Fireplace

    Another irregularly-spaced LED project. (See my last one here: LED Display with Irregular LED Spacing)

    This was a quick one-day holiday project with some cardboard, paper, a Teensy 3.1 and the...

    This is great thanks! I thought FastLED was a driver like OctoWS2811 but the fact that I can use the FastLED API and OctoWS2811 driver is great.

    So far I only tested FastLED with my LED strips...

    Does FastLED library work with OctoWS2811 Adaptor?

    I also have this question.

    Since the product page says the following, I am not optimistic:


    This adaptor board connects Teensy 3.2 - Teensy 4.1 to thousands of LEDs using the OctoWS2811...

    Just returning to this post to ask a follow-up question. I just learned about I2C protocol:



    Any reason why this wouldn't be a good idea for my application here?

    Hi Epyon. Where did you get this 90-degree angled sockets (2 rows of 6). I am looking all over DigiKey and can't find something similar. I need 2 rows of 7 to mount on an OctoWS2811 Adaptor.

    Unfortunately I had to solder it down due to height limitations. Since we're on the topic, the 14-pin sockets that come with the Teensy are pretty high. Can you get shorter ones so that the Teensy...

    Thanks, I didn't know that using A8 was possible. I tried it but it doesn't solve the problem.

    I tested the voltage at pin 22. It's 2.51V when the photocell is connected and 0.00 when I had the connecting wire across the pins as shown in the photo above. (Board VIN is 4.76V, and the 3.3V pin...
  12. Can't get AnalogRead working on Teensy installed on an OctoWS2811 Adaptor

    I'm trying to use analog input on a Teensy connected to an LED array so that I can add a photocell to adjust the LED brightness.

    I made a simple test script and it works on one Teensy 3.1 but when...

    Okay. Sounds like I don't know what I am talking about... I guess I need someone to tell me how to do this.

    Thanks @tonton81 but can you please confirm exactly how to implement that in the code? Do you mean use pinMode(14, INPUT_PULLDOWN); in the setup() part of the code? Will that add a pulldown...
  17. Are the internal pulldown resistors on Teensy 3 for digital input only (not analog)?

    I assume the answer to this is yes (only for digital input) since I can't find any reference to using a built-in pull-down resistor on the analog input pins here or here or on this forum.

    If...

    Thanks KurtE. I may look into that method but I already solved that problem. I used some serial communication whereby each Teensy is asked to report who they are and then they are thus identified...

    Actually it was the third one in the first strip! This was one of three that I separated from the other boards so perhaps I damaged it when I did that.

    Is it something to do with power consumption? I have 2x 50 leds running off the teensy which is plugged into my MacBook Pro via USB. Should I be moving to a dedicated 5V power supply?
