Key Block + Block




This project shows you how to complete a circuit through two boxes.

Step 1: Step 1: Cut and Glue Cardboard

Gather cardboard from boxes and cut them into these measurements:

4 7" 1/2 by 7" 1/2 of cardboard for box

4 9" by 9" for key box

both widths 3 inches

You will be making two boxes, one for the key and the other for a regular block.

Once you have everything cut up into the correct measurements, glue them together to create a square shape.

Step 2: Step 2: Cut and Glue Diffusion Cloth

Gather Diffusion Cloth and cut it into a 7 1/2" by 7 1/2" and 9" by 9" square. After you finish cutting it, glue it only to the cardboard box with the corresponding measurements.

Step 3: Step 3: Copper Tape

Once your block is made, place copper tape around the perimeter of the box.

Step 4: Step 4: Makey Makey and Scratch

  • Connect Makey Makey to the computer
  • Open up Scratch on the computer
  • Connect a wire to the ground on the Makey Makey
  • An alligator clip will be connected to your desired key (spacebar)
  • The other end will be connect to another wire that will be connected to the box (step 6 shows you how it will be connected)

Step 5: Step 5: Scratch Instruction

This step will show you what to program scratch so that a sound will be made when the copper tape is touched.

  • Click "Events"
  • Drag "when _____ key pressed" onto the space on the right
  • The little black arrow pointing down will allow you to change which key you want to press to make an outcome. In this case, it will be space bar.
  • Next click "Sounds"
  • Drag "play sound _______" and drop it right under the "when _____ key pressed" you dragged out earlier

Step 6: Step 6: Connecting Program to Block

  • Once you have the program up with all the wires and your desired action in place, you will now connect the wires to the box.
  • With your wire, bend the metal so it will be horizontal when you hold it up.
  • Lift the copper tape
  • Make a tine hole in the box where the copper tape once was
  • Insert the bent wire through the hole and place the horizontally.
  • Put the tape down to where it was before, but this time with the wire underneath it.

Step 7: Step 7: Connecting to Key Block

The Key block is connected directly to the Makey Makey through a wire that is connected to the ground.

Step 8: Step 8: Enjoy Your Boxes!

Now when you hold the key block and tap the other box, it will make the effect that you chose through Scratch.
