Infinity Gauntlet
This Instructable will explain and show the user how to create a homemade infinity gauntlet through the use of led lights, Arduino controller, and other components. The Gauntlet main primary function are LED patterns and audio through the activation of a pushbutton.
Some Guides Soldering, Arduino Coding, and cardboard crafting for Any Confusions:
Supplies
Computer for coding
Cardboard box
Exacto Knife
Wire Cutters
Scissors
Gold Acrylic Paint
Prep Your Resistors
Trim 6 68 Ohm resistors for the LED's and 4 17k Ohm Resistors for the breadboard to 1/4 in length using wire cutters.
Attach the Resistors to LED's Using Solder
Using a Soldering iron, Attach the 6 68 ohm Resistors to six different colored LED's. This will prevent the light from burning up during use.
Cut Electric Wire Strips and Attach LED's
Using Wire Cutters, Cut the Black Electrical Wire from the spool 12 5 inch wires and attach one wire to each end of an LED.
Wrap LED's in Electric Tape to Cover Exposed Wire
Cut 12 2 inch strips of electrical tape using scissors and wrap around the exposed wire.
Mark the Resistor Side of the LED
Using a Highlighter, Mark the cut electrical wire attached to the resistor side for all LED's. This will help later in the assembly process.
Attach LED's and Speaker to Glove
Use Hot Glue to attach LED's and Speaker to the back of the glove.
Attach Breadboard and Arduino to the Glove
Peel the back of the breadboard and attach it to the palm. Attach the Arduino to the back of the glove on gold side flap with hot glue.
Wire Breadboard and Ground LED's
Copy the circuit in the first photo which utilizes the 4 trimmed 17k ohm resistors, .4 jumper cables, and 4 push buttons. Cut another 5 inch electrical wire using wire cutters and attach the 5V from the Arduino to the positive side of the breadboard. The electrical wire attached to the non resistor end of the led is wired across the glove over the thumb into the ground on the breadboard.
Wire Breadboard and LED's to Arduino
Wire each of the lights resistor ends to pins 1-6 on the Arduino. Wire the positive speaker side to pin 12 and ground it on the Arduino. Wire each pushbutton to pins 7-10.
Attach Battery Pack to Glove
Attach the battery pack along the space between the pointer finger and thumb to keep it close to the Arduino.
Cut Carboard Pieces and Strips to Cover Exposed Wire
Cut 3 4" long 4" wide pieces of cardboard and 4 6" long 2" pieces of cardboard using the exacto knife.
Combine and Attach Cardboard to Glove
Cut small 0.5" holes for each LED lights on the back of the glove and a one inch by one inch hole for the speaker. Use Hot Glue and Tape to attach the cardboard cutouts onto the glove creating a gauntlet like exterior.
Connect the Arduino Cord and Tape Arduino Cord to Cardboard Underneath
Connect the Arduino cord from the battery pack to the Arduino. Using electrical tape, Tape the Arduino cord to the underside of the cardboard to hide it from view.
Coding the Arduino and Uploading
Copy the code below and upload it to the Arduino from your computer.
