Section IV. Summary
Congratulations on completing the ScioBot 1.0 build! Enjoy your robot and experiment with di
ff
erent wiring
configurations to learn how di
ff
erent applications of electric currents a
ff
ect the operation of DC motors. You
have also learned the basics of using a breadboard to prototype an electronics project. Breadboards are an
essential tool when working and experimenting with electronics and engineering. By giving you the
opportunity to easily reconfigure, upgrade, and extend your prototypes, breadboards accelerate your ability to
complete projects.
EXPERT TIP:
On the back side of each motor there is a + sign. This
allows you to identify the polarity of each motor.
Applying a positive current to the + side of each motor
will cause them to rotate in the same direction. While
this is the case in a testing environment, because our
motors are facing 180˚ from each other, this will cause
the wheels to rotate in opposite directions. In order to
know that the wheels will rotate in the same direction,
we must connect the + lead from one motor and the -
lead from the other motor to the same row on the
breadboard.
