Step 1: Get three pieces of 9.7*6cm cardboard

Step 2: Glue them together like the second picture above (I used hot glue)

Step 3: Put your completed circuits plus the breadboard and the Arduino board into the slot made by cardboard

Step 4: Cover it up with paper or any materials that are able to be seen through in order to make sure the light shines through

Step 5: Add any pizazzes you want on it

Test It Out!
