Gotcha. I was more wondering if your resistor values and such were set in stone yet. I'm still dragging my feet on an IR sensor PCB. Going to stick with the TCRT5000 and n-channel MOSFETs for now. I've got the resistor values and such more-or-less figured out, it's just the physical arrangement giving me problems, how to make a compact board with an I2C interface, that I can arrange in a variety of positions and directions. I whipped up one board already, but it's a little over-engineered for a first prototype. It's getting binned and a simpler one made up today.
Alright. I'm now facing a bit of feature-creep with my bot here. The more I work on it, the more I learn, the more ICs I come across and want to try out, the more the scope keeps expanding and, I'll never finish at this rate. I'll make a PCB, it'll have some little bug with it that I want to fix, and since I'm scrapping the traces and layout I might as well optimize the layout, and add this IC, and this feature, and two more of these… ad infinitum. So I'm going to go ahead and do something I should have done a long time ago, lay out the detailed design goals for this project.
What it is:
1. Autonomous floor-dwelling "micro mouse" style robot.
1. Further my robotics education.
2. Allow me to make modules that can be reused or expanded on for other projects.
What it will do:
1. Explore it's environment autonomously.
2. Be rechargeable.
3. Send telemetry back to a base station.
