Nine Sided Digital Dice

Introduction: Nine Sided Digital Dice

Reference: https://www.instructables.com/id/Arduino-Led-Dice...

I have added two more LEDs.

The Instructables will show you how to create a special digital dice that can roll out numbers one to nine by using Arduino. It is a simple project, and it is suitable for beginners and those who want to start with Arduino.

Step 1: Things You Need

Parts:

Arduino 9x LEDs of any kind

A 10k Resistor

9x 220 or 330 Resistor

A little Push Button

Breadboard

Some wires for the breadboard

Tools:

The Arduino programmer

Usb Cable A-B

Step 2: Place the LED on the Breadboard

Place LEDs in shape of 3x3 square. It is really difficult to find the right configuration without superimpose the LEDs. However, there is a facilitate picture that shows where should you place the short leg of LEDs(cathodes) and where should you place the long leg(anode). I group them into six groups. First group is upper left one and lower right one. Second group is middle right one and middle left one. Third group is upper right one and lower left one. Fourth group is the middle one. Fifth group is upper middle one. And the last group is lower middle one.

Step 3: Place the Resistor

Connect all the cathodes of the LEDs to ground with resistors.

Step 4: Place the Button

Place the pushbutton on the breadboard and connect it to ground with resistance.

Step 5: Connect the Anode With Arduino

Attach the Arduino ground with the ground line of the breadboard.

Connect the LEDs to Arduino. This part is quite complicated. However, there is also a facilitate picture for that.

Connect the 5v of Arduino with the button, and connect the button with the pin 6 of Arduino...be careful also in this part and follow the picture.

Step 6: Code

    Neat adaptation - congrats on your first instructable. Why did you pick the numbers 1-9 ?
