Parts You’ll Need From Your Invention Lab
The following parts from your invention lab will be needed to complete this project.
2 x DC Motors:
Note: This instruction manual was first
produced using an older model of DC
motors. We have since upgraded the DC
motors in the Invention lab. At the time
of this printing, the motors above are the
motors to use for these projects.
These motors have female pins you can
plug your DuPont cables easily into.
1 x NPN Transistor
This will control the launcher’s speed.
The Battery Power Adapter (6 x AA
Batteries)
You’ll need this to power the launcher. It
takes 6 AA batteries (not included).
1 x Digital Servo Motor
This will move a cam that sets the
trajectory angle of the launcher.
2 x Potentiometers
You will use these to change the speed
and pitch of the launcher.
