It's been more than a week. They were supposed to have been shipped via USPS. The vendor is not answering its email. Does not look good.

Meanwhile I might as well get back to the REAL project. I have not decided on the least intrusive means to generate PWM. Using the toy level car all I have is bang/bang control. Full speed forward, full speed backward, stopped. Full turn left, Full turn right, straight ahead.

With PWM control I have CONTROL. Thing is, I do not know whether I really need this complication. Probably not. But I do need for the microprocessor to be doing things while the car is moving. PAUSE does not cut it.

Gotta put back on my thinking cap.
