An overview of the 8x8 led matrix with a ht16k33 backpack.

Ht16k33 led backpack arduino. Codebender includes a arduino web editor so you can code store and manage your arduino sketches on the cloud and even compile and flash them. These 14 segment displays normally require 18 pins 4 characters and 14 total segments each this backpack solves the annoyance of using 18 pins or a bunch of chips by having an i2c constant current matrix controller sit neatly on the back of the pcb. Arduino leonardo arduino micro arduino yun teensy 2 0. One of the first displays i pulled out was the 8x8 led matrix with the ht16k33 backpack.

Adafruit industries unique fun diy electronics and kits adafruit 14 segment led alphanumeric backpack id. The backpacks all use the ht16k33 chip solely for led driving the mini 8x8 s use the 24 pin version and the others use the 28 pin vesion ht16k33 8x16 led backpack breakout schematic fabrication print. Atmega328 16mhz. The ht16k33 is a neat little chip that has the ability to drive a multiplexed 16x8 matrix that 39 s 128 individual leds.

These backpacks feature an ht16k33 i2c led driver they re simple and easy to use you can use our very nice library for the backpacks to get running in under half an hour with numbers and. This is a random number generator using 8x8 led matrix and arduino.

It is adjustable from 1 to 60 and includes a timer play mode. 1427 this is the magic sauce in our 7 segment and matrix backpacks now available in breadboard friendly breakout board format. Arduino ide in the cloud. I have seen them before and to be honest i got it because it looked fun.

For the demo sketch i m using a 16 bit buffer which makes each array element correspond to all outputs for a given com pin you could also use an 8 bit buffer which would make things easier if i only had 7 segment displays. The functions included in this demo sketch should be all that s needed to control the ht16k33 s led matrix from an arduino. 1910 by popular request you can now get our 14 segment led backpacks without the leds.
