Minimal CPU impact and double buffering allows complex animation. Safety First LEDs can produce extremely bright light.

Please use caution when viewing large numbers of LEDs at close distance. A diffusing material in front the LEDs is usually a good idea.

74HCT Datasheet

Large LED arrays consume considerable power. Appropriate wiring should be used. AC mains voltage should be wired properly according to electrical codes.


Fewer or shorter strips may be used, with addressing described below. Teensy LC Pin Teensy 3. This PWM pin and the timer must not be used. See the dtaasheet above for details. Modern versions do not use pin 15 or Approximately LEDs per Teensy 3.


Any number of Teensy boards may be used to support large LED arrays. The video dahasheet sync signal must be connected to pin 12 of all the boards.

You can only create a single object, but it must be created with these parameters: The number of LEDs connected to each pin, or maximum number if different on each pin. The memory used for display data.

Use an array of “int” 6 times ledsPerStrip. The memory used for drawing operations. Start an update of the LEDs. This function returns within 2 microseconds. The display update continues, taking 30 microseconds for for each LED, plus 50 microseconds to reset datashdet WS If called while a previous update is running, this function waits for previous update to complete and then starts a new update.

Check if a previous show is still running. The number of LEDs connected to each individual Teensy 3. Zig-Zag layout of rows from each strip. The upper right corner of the portion of the video this Teensy should display. These numbers are percentages, from 0 to When using only one Teensy, set these to 0, 0.

The size of portion datasbeet the video this Teensy should display. When using only one Teensy, set these to Processing can transmit video to any number of Teensy 3.

Place resistors close to the Teensy pins. Data flow with OctoWS
