DJ Create
So you want to impress your friends with a roaming,
robotic DJ at your next party, but that speaker that you
glued on top of your Create
®
2 keeps getting knocked
off. Follow along here and see how you can build your
own DJ Create.
Get ready to rock with a roaming, robotic DJ! We will
show you how put two speakers and a Bluetooth module
into your Create 2 bin for less than $15 in parts.
Overview
Preparing your electronics
1) Remove all of your electronics from their packaging
and lay them out on your work surface.
2) Choose which speaker will be the left and which will
be the right and label them accordingly.
Wiring the audio amplifier board
1) Connect each speaker to the corresponding screw-
down terminals on the amplifier board. Be careful to
observe the correct speaker polarities, but getting
them wrong won’t blow anything up.
2) Connect the battery holder to the corresponding
power connections on the amplifier board. Be careful
to observe the correct polarities—positive voltage to
the “+” terminal (usually a red wire), negative to the
“-“ terminal (usually a black wire). Getting this wrong
will likely damage the amplifier.
