Building the Servo and LED Circuits
It’s really important to be careful when connecting a servo to your BASIC Stamp. How
you connect your servo depends on whether you are using the Board of Education Rev B,
Rev C, or the HomeWork Board. If you are using the Board of Education, but you’re not
sure which Rev it is, Figure 4-2 shows an example of the Rev label on the Board of
Education Rev B.
