Arduino Led Dice

Step 3 Schematic & Intro

To create all the six faces of a dice, you need 7 LEDs, placed in the shape of an "H".

As you can see from the diagram, they're not all linked to different pins of Arduino, but most are connected in pairs, to facilitate the use.
To create all the faces of the dice, you must follow these rules:

For the number 1 of the dice: lights up the led 4
For the number 2 of the dice: lights up the group 1
For the number 3 of the dice: lights up the groups 3 and 4
For the number 4 of the dice: lights up the groups 1 and 3
For the number 5 of the dice: lights up the groups 1, 3 and 4
For the number 6 of the dice: lights up the groups 1, 2 and 3
