There was a holdup with running code from Standard Servo manual.
I had to go over to What's a Microcontroller servo chapter to see how to connect servo to BOE.
Found out Standard Servo is a 180 degree servo.
Got the Boebot chassis out to see what kind of servos are on it. You can't see label when they are bolted to chassis.
Have to figure they are continuous rotation. Would take reading Boebot manual to confirm that or unbolting them.
I'm probably more interested in continuous rotation servos than a 180 one. Really DC motors but will do this lesson.
EDITFound Parallax lessons on DC motor control. In Process Control manual. Chapter 5
They look pretty good.
