TARGET PRACTICE: GAME OF THE FROG

Introduction: TARGET PRACTICE: GAME OF THE FROG

Hi there! Today we are going to play a typical spanish game: The game of the frog is a target game where you have to throw coins into a box and make them cross through one of the holes on its cover. Every winer coin will give you points. Special holes will give you a higher score. In the original game, a little frog is placed is the middle of the cover and if you get a coin through its mouth you get the highest score. In this project building the box will take you some time, but the program used is really basic level.

Supplies:

  • A cardboard box
  • A cardboard tube
  • Adhesive conductive tape
  • Adhesive tape
  • Scissors
  • Makey Makey kit
  • Scratch (online or desktop version)
  • Paint

Step 1: Prepare the Cover

Draw and cut the circles for the coins in the cover. The size of the circles shouldn't be too big. Place a piece of cardboard in the edge to avoid coins going away if you don't score. You can also use some spare cardboard to increase the difficulty of the game. You can recall the original frog with the carboard tube.

Step 2: Create the Switches

I used folded carboard pieces to work as switches. Each side is connected to a circuit branch (earth or a key) and when it is folded because of the of the coin weight, both sides touch each other and the circuit is closed. Cut the switches and place them in the bottom of the box. First, I cut them in cardboard but as they needed a really heavy object to be closed, I re make them out of paper. Draw the circuits with marker to make sure you can connect all the "Earth" wires together and the circuits for the keys with enough space between them. Paste some adhesive conductive wire in the inside of the switches so when a coin closes it the circuit is also closed.

Step 3: Build the Circuits

Paste adhesive conductive tape all over the drawn circuits and join them to the switches.

Step 4: Electrical Connections

Open a hole at the back of the box and use spare adhesive conductive tape to connect the alligator clip cables.

Step 5: The Scratch Program

The Scratch project is really simple: you have to make a variable for the score. Then, you only need to add the Makey Makey extension and configure each key to increase the variable. Remember, the "tube hole" will change score by a higher number. If you want to have a look at it, here you have the project page.

Step 6: Decorate!

Paint your box and add some details, and that's it! Play it and have fun!
