Every official arduino board (and many unofficial ones as well) support I2C. The arduino team has published a library and example code on how to send and receive I2C commands, so if you've worked with an arduino before it shouldn't be too hard to modify it to your needs.

Maybe one day there will be an EZ-Bit IO expander wink wink

I like Rich's idea of using an Arduino to handle fast acting automated tasks like keeping balance. I have a book about using Arduino for robotics, and one of the samples is actually not a robot, but a Segway clone. Not on my current project list, but I could see wanting to make a self balancing 2 wheel bot, letting the Arduino handle the balancing part, and receiving forward/backward/stop/turn commands from an EZ-B that also handled all of the more interactive functions.

I need to finish my first two planned bots before I dip my toes in that water, but maybe I won't sell my remaining V3 EZ-B after all (I just pre-ordered another v4 developers kit. Decided to get in before any price increase rather than waiting and needing to sell the V3 to afford it -- I was torn between a Roli, which I think is a bargain, but I already have a 90% complete treaded bot, An Acer W3 to embed in my bigger bot instead of my larger and heavier Panasonic Toughbook, or just go for the V4 kit. Decided to go for the kit for now. Acer W3's will only go down in price, and at my current rate of robot building I won't be ready to put the computer in the big one for another 6-8 months anyway).

@Herrball and @Rich ...further to the I2C and Arduino
arduino.cc/en/Tutorial/MasterWriter and

www.instructables.com/id/I2C-between-Arduinos/ if you havnt found them already @Alan A self balancing type Segway would be very cool.....I think every person on this Forum understands your " in progress bots"

Hello Herrball, I am trying to make a pair of eyes for my son's four foot high toy soldier. I am new to this - is there any chance you could create a kit of the hardware and software ready loaded so that all I have to do is purchase the kit from you and then plug a few things together?

regards Shaun

I have be thinking about putting together a video on these eyes as several people have been asking about LED eyes lately. It is very easy to do and I think after you see what is involved you might take the project on for yourself. I would be more than happy to supply the code that I have. I have never done a video so this might take me a little time to get it setup but I'll give it a shot.

1. get the EZ-B v4 I2C Peripheral Cable (25cm)

2. check the ezb data sheet for the +5, gnd, clock and data lines from the i2c port

3. connect the corresponding 4 wires from the EZ-B v4 I2C Peripheral Cable (25cm) to the led matrix. It has labels for each Of the four wires. Connect the plug to the EZ-B v4/2 Wi-Fi Robot Controller

4. load ARC

5. add control -> i2c -> led matrix 8x8

6. press the configure on the control and you can create animations with the mouse

Yup, DJ is right as usual.

If you look up Luis Vazques https://synthiam.com/User/luis-vazquez/Profile/

He on this forum he taught me to do this using arduino and EZ-B. Both together talking via serial is amazing and very easy to do. You have unlimited code and examples on the arduino.

This is arduinio and EZ-B working together. Learn to make the two communicate and you will not be disappointed.

Love the neo pixel rings in your bot!

The arduino is great for controlling single simple thingd and yiure right, has a huge library of code. Combine that with ezb and off to the races!
