Cardboard Jackpot Game

by JackANDJude

Published on August 16, 2016

Test your reaction time and win REAL MONEY when you play Cardboard Jackpot.  Press the button when the bargraph shines red to advance to the next round until you win 3 rounds and earn the Jackpot prize!  This invention uses bits and accessories from the Arduino Coding Kit, plus cardboard, balsa wood sticks, and a pen.

Duration: 2 hours

How To Make It

STEP 1 : Assemble Circuit on Mounting Board

4750c31a 38ee 4851 b63e 0532ee859967

Build this circuit on a Mounting Board: battery & cable + p1 power + fork + button on top bitsnap to d0 pin on Arduino + dimmer on bottom bitsnap to a1 pin on the Arduino + bargraph on pin d5 (analog) + servo (turn mode) on pin d9 (analog).

STEP 2 : Upload sketch to Arduino

With the Arduino IDE already installed, connect the Arduino to your computer with the white micro USB cable and turn on the power switch. Save "Cardboard_Jackpot_Game.ino" to your Arduino folder, and open with Arduino. If prompted, allow the software to create a folder for this sketch. Once the sketch opens, select Arduino Leonardo or littleBits Arduino as your board and select the correct port. Upload the sketch, and wait a moment for the Arduino to blink Tx and Rx leds. Upload is a success when you see the bargraph repeatedly cycling like a marquee sign.

STEP 3 : Build Cardboard Enclosure

Cut seven pieces and assemble with glue. Dimensions are in inches: 1) back wall: 11"x8". 2) floor: 11"x10". 3&4) side walls (see photo). 5) center support is a right triangle 2" high, 6" long. 6) play surface is 11" across x 10.5" deep, with a 7" across x 4.25" deep rectangle cut out of back left corner. 7) interchangeable sign is 11 x 4, and propped up with two toothpicks. For a better idea how to put all this together, see tinkercad link in description.

STEP 4 : Build a coin ramp

Glue 3 balsa boards together with a channel narrow enough for one coin to roll through. Add 2 more balsa boards to create a second channel if you like.

STEP 5 : Put it all together

Cut a hole on the left side of the box for the coin ramp and a slot on the cardboard ramp to secure the bottom of the coin ramp. Connect the servo hub and mechanical arm to the servo and insert a pen to the mechanical arm hole. On the other end of the mechanical arm, insert a toothpick taped to a 1" cardboard square. Test servo interaction with coins and coin ramp with this temporary circuit: power + button + servo. Hold up the servo to the back wall until you find just the right spot to cut a snug rectangular hole. Secure the servo in the the back wall with one screw. String the servo wire under the coin ramp. Reassemble your full circuit from step 1 on the mounting board and attach the mounting board to the center of your play area with two screws at the top corners.

STEP 6 : Play & Remix

Play with friends and see how you like it. Change the Arduino code to make the game easier or more difficult. Choose a theme and decorate how you like. Take pictures and video of your remix and upload it for everyone else to see.
