Includes 3 playable games, speakers, LEDs, a power button, and wired power supply.
Medium Density Fiberboard Rings with embedded radio frequency identification (RFID) tags and a 3D printed hollow dowel which houses an RFID sensor
A microcontroller tracks the order in which rings are stacked. As the rings pass over the dowel, the tags are scanned by the sensor in the dowel.
Each ring has an associated musical note that is played with the ring is stacked.
Medium Density Fiberboard Animal Cutouts with handles and peg
Peg actuates a switch when cutout is fully inserted.
When the switch is actuated, an associated animal sound is played.
Shapes and the housing are both 3d printed using PLA. The shapes house neodymium magnets, and the housing contains hall effect sensors, and LEDs.
When the shapes are fully inserted, the magnetic field from the magnet interracts with a hall effect sensor, which sends a signal to a microcontroller.
LEDs illuminate when shapes are fully inserted.
The sensor modules are located behind the shapes, within the hub. When a shape is placed in its respective slot, the attached magnet will interact with the hall effect module, redirecting current flow through a different path, outputing a signal to the arduino. The arduino reads the signal and turns on the corresponding color LED above, indicating the correct shape has been placed into the correct slot. When all four shapes are successfully inserted, a celebration sound will be played from the soundboard.
The RFID reader will be located in the dowel, constantly emitting a perpendicular, bidirectional signal in the 13.56 MHz frequency domain, waiting for a return signal from the tag located in one of the 3 rings. The tags used for this project are passive devices storing hexi-decimal numbers that “bounce” a radio signal back towards the reader with the hexi-decimal number as data. When this occurs, a 4.5V motor spins the yoshi figurine located on the tiny dowel. Each ring has an associated musical note attached to it, so when the large ring is placed, a low tone will be played from the soundboard. The medium sized ring has a mid tone, and the small ring has a high tone. When all 3 rings have been registered as placed on the board in large to small order, a celebration sound will play from the soundboard, signifying a successful task completed. When the rings are placed in any other configuration, a different celebration song will play, signifying a good attempt.
The limit switches are located at the bottom of the opening of each animal cutout. They redirect the flow of current when pressed by the pegs located underneath each animal shape. For each switch, there is a corresponding animal sound that plays from the soundboard when the switch is pressed. When all animal pins are placed in their slots, a celebration song will play, signifying a successfully completed task.
