Is There A Way To Connect A Led Matrix To ARC

Skip to comments   Jump To End

i am working on building my first robot and i have 2 Bi color led matrix. is there a way to hook up the matrix to the ARC or do i have to use a I2C to connect it to an Arduino to control the Matrix?

the Matrix i am using is Adafruit Bicolor LED Square Pixel Matrix with I2C Backpack. i was able to get it to work with Arduino, but i want to send data based on a camera tracking my face. Thanks

Hi @Greschel14

The ez-b also has I2C ports that you can control it from.

Please see the Datasheet

Pinout from left to right: GND, 3.3VDC, SDA, SCL

Not quite sure what your asking here. I use this led matrix setup on my robot ... http://letsmakerobots.com/node/37367 All the eye programming runs off a mini Arduino Board, so as not to waste computing power of the EZB. It will randomly look around but whenever I need it to look in a certain direction or expression I just send it a serial command from the EZB.

Hope this might help you in some way.
