@zander I think Bill has mentioned he as had the best luck with solderless breadboards from Jameco Electronics, but you might ask him to verify. I...

@davee & @zander, Well I sit here with egg on my face. All is working as it should! Even after all my double checking of wiring it seems I had...

@byron Thanks for your comments. The objects and classes idea is great, but for this application which was some test code only, I'm going to leave...

@zander and @davee I'm on it like ducks on June bugs. Will report back later!! Thanks for your help.

@davee OK Dave, I liked and tried your suggestion. Moved the MR_BI2 from GPIO pin 2 to GPIO pin 15. Just a one position move on the wiring coming ...

@davee Thanks for that! Maybe that's it. Don't really need those asterisks, I was just providing a "border" between each wheel in the code. If...

Finally got back to working on my Mecanum Wheel robot car! Have all four wheels connected to the test bench setup that includes the two TB6612FNG mot...

@jrrobb, Jim You are misunderstanding the 3.3v supply for the TB6612FNG. It is not supplied from the motor driver board but to the motor driver boa...

@zander I believe there was an interim update to boards and/or libraries that broke analogWrite. Mine was originally working, then when I went to ...

@jrrobb Jim, I just wired up one channel of one TB6612FNG, the right front, according to Bill's diagram, and using the attached "4wd-test2.ino" fi...

@jrrobb Jim, I'm actually planning on getting back to this project this weekend, maybe even a bit today. My vision is vastly improved and ready ...

@zander, @jrrob, And it gets even stranger! For the past few days while using IDE v2.1.0 I was never prompted by a message that there were any upda...
