Automatic Card Dealer

The Automatic Card Dealer is a mechatronic device designed to complete the task of dealing cards. The device utilizes an Arduino microcontroller, a continuous micro servo motor, a positional micro servo motor, an ultrasonic sensor, and the associated circuitry and mechanical structure.

Operate the device by clicking the button, and the device will stop and output two cards when it "see's" an object in front of it.

Arduino UNO

Wire Kit

Push Button

1000 ohm resistor

Micro Continuous Servo

Micro Positional Servo

4 Wire Harness

Mini Bread Board

HC-SR04 Ultrasonic Sensor

Card Cage (3D printed)

Card Wheel (3D printed)

Foam Board (20x30 sheet)

For the baseplate, cut a roughly 6” x 6” square of foam board.

For the stem, cut a roughly 4” x 3” piece of foam board, and fold it around your positional servo as seen below. Proceed to glue the folded structure along the open edge, and glue the servo into place at the top.

Glue the stem to the center of the baseplate, being sure to route your servo wire between the baseplate and stem

Begin by gluing the card wheel to a servo horn on your continuous servo.

Glue the servo, a servo horn, and the ultrasonic sensor to the bottom of the card cage as seen below. Take caution to ensure you are gluing your servo and ultrasonic sensor on the side of the card cage that has the slit.

Because your card cage already has the servo horn glued on, and the base has the servo, simply place the card cage on top of the spline of the servo on the base.

Assemble your circuit on your Arduino according to the image of the following diagram. Feel free to simplify to a smaller breadboard. Just be aware, if you change pins, you will have to adjust your code accordingly.

Upload the attached code to your Arduino. If you used different pins in your circuit, adjust the code accordingly.
