Introduction: Arduino Blue LED Dice
Thanks to nick_rivera for the credit
This is the Arduino dice that can be used in types of board games and the numbers are shown randomly.
Step 1: Materials
What you will need:18 Jumpers
7 LEDs (I used blue ones)
Resistor (I used 100ohm, 10 ohm would work too)
Arduino Leonardo(+usb cable for connection)
Knife to dig hole
Step 2: Arrange the LEDs
Start arranging them onto the board, having the negative side of the LEDs point to the left.
LED 1 goes between pins (1-,2+)
LED 2 goes on (5-,6+)
LED 3 on (9-,10+)
LED 4, in the middle, must be stretched between (4-, 7+).
The last 3 LEDs go directly below the first 3 LEDs, but on the other side of the breadboard.
Step 3: Connect the LEDs to Ground
Take your jumpers and connect all of the negative(-) sides of the LEDs to the ground rail.
Step 4: Jumpers Connect to Arduino
Get out your large jumpers, and put a jumper onto each positive(+) side of the LEDs. It is much easier if you color code the jumpers, it will help later. Also, connect a large jumper to the ground rail, and that will connect to the ground on the Arduino.
Now, we connect the jumpers onto the Arduino board itself.
Step 5: The Pushbutton
Now, we connect the pushbutton. Start by placing the big and black button on to the board. (see the diagram for further understanding).
Step 6: Arduino Code
I change the delay time from 5 seconds to 1 second.
Step 7: Set Up the Cage
Prepare a shoebox and a knife to dig the hole for the LEDs and the pushbutton. Be careful when you are cutting the box. YOU DON'T WANT TO HURT YOURSELF!!!
