6) Power Supply
Depending on the varikabi model, you can,
for example, lead the battery's two plug-in
connections from below and through the gap
between the motors and the battery.
Then insert the black (-) and red (+) contacts into
the outermost rows on the breadboard.
Now, slide the two white rubber grommets onto
the LEDs.
Always use the clip connector on the battery to
turn varikabi on and off.
To avoid a short circuit, leave the
plugs in the breadboard.
