CHAPTER 22 ■ SOLDERING AND CONNECTING- Insert the remaining wired terminals into their housings.
Facing the windows in the housing with the wires pointed downward, I choose to connect the negative
wire from the motor on the left side, and the positive wire on the right. It doesn’t matter so long as you’re
consistent with your circuit board and both motors.
- Hold the motor in one hand and the connector housing in the other hand.
- Twist the housing about ten times, so that the pair of wires twist together
(see Figure 22-20). Not only does this prevent the wires from becoming tangled
with other wires in the robot, but also it cancels out some of the electrical noise
generated by the motors.

Congratulations, the motors are complete! The motors now have color-coded wires soldered to them,
the terminals and solder joints are protected with plastic heat-shrink tubing, and the wire ends in a
finger-friendly connector.
