LESSON GUIDE

STEP 1 : Collect your bits

You will need the battery, power connector, power bit, button bit, long wire, and servo bit. Besides littleBits, you will need packing tape, rubber bands, paper clips, and a mounting surface (a cd spindle case works well. Also a puppet (you can make your own out of paper or an old sock!).

STEP 2 : Connect the bits

Plug in the battery. Connect the power bit to the button bit. Connect the button bit to the long wire. Connect that to the servo bit. Set the servo bit to ‘turn’ mode.

STEP 3 : Prepare the servo

Use rubber bands and paper clips to give the servo ‘arms’.
STEP 4 : Mount the servo

Using tape or other mounting materials, affix one arm of the servo permanently to the mounting platform (top of cd container in this case).
STEP 5 : Add the puppet

Now stretch the puppet over the servo arm, so that the top half of his mouth has the arm stuck in it. You now have a working puppet bot!
