I have taken a couple of years off of this omnibot 2000 build. I kind of get stuck, frustrated and quit. Then every no and then I comeback and look at it again. I have watched a lot of the videos people/bot have recommended and I'm still stuck. Mostly this is because I'm not an electrical engineer...LOL I know how to take things apart and monkey with stuff. I can solder and follow instructions but this project has stalled. My main issue is that the videos go to fast and are not detailed enough for my limited knowledge. So here is where I'm at. How do I wire the hbridge to the ezb and battery and how do I wire the 8 motor wires to the hbridge? Here are a couple pictures to show what I have going. Thanks in advance for any advice.

hey ptp is this what you are looking for?its the second pic.
@Nomad 6R I don't see I2C (SDA, SCL) pins anywhere....
but CMC206 mentioned he plans to use I2C port and the RGB control.
To me looks a plain raw "neopixel" maybe CMC206 has more info from parallax ?
ah the 3 ports on the ezbv4 is 12 c is ( sda, scl )thanks learn some.
No dice! HELP!!!
I have the three pins on the right soldered in. S1, +5, and GND. I tried putting it on a d10 an ADC0. Obviously, I have no idea what I'm doing but no light.
All of the tutorials have broken links or no video on youtube. Looking at the picture above do you think it takes all 6 pins? I'm stumped.
If anyone has any advice on what pins to connect to and what control to add I would appreciate it. All I want to do is give this bot some eyes.
Thanks,
CMC
Looking at the datasheet it looks like you need 4 pins. The Top left would be 5v pwr. Bottom left is signal out. Top right signal in and bottom right gnd.

@CMC206 I assumed when you mentioned I2C it was an I2C device.
Looking to the specs that is a neopixel and you cant connect directly to the EZB.
you need a neopixel controlller and or an arduino or a parallax controller with custom firmware.
Search for neopixel to get an idea of what it is.
Thanks I will look in to that. I thought it was worth a shot because they were cheap.
The Parallax LEDs were a bust. I got some BlinkM LEDs and now I'm waiting for the camera extender and IC2 cables from EZ-Robot. In the meantime, I'm looking at putting a servo in the head to do just left to right movement. I'm going to put the camera in between the eyes to do movement tracking. What I'm looking for are any pics or advice on how to mount the servo in the Omnibot 2000 head. What parts to toss and what parts to cut and the alignment of the servo. From pausing DJ's video it's not quite enough and it looks like the head would be a weak point if someone was to pick it up by the head. I know there might not be a way around that but I want to start off in the right direction.
Thanks,
CMC
