ATtiny85 LED Dice

Today I will show You my new project - LED Dice using a ATtiny85.

When You press the button, it generates a number randomly and displays it as a die.

Parts:

• ATtiny85 (also You can use ATtiny45 and ATtiny25)
• DIP8 socket
• 7 green LEDs (3V)
• Tact switch
• 10kΩ resistor
• Single side perfboard (12 x 22 holes)
• 2 batteries with holder

You also need:

• Wire for making paths
• Heat shrink tubing for isolate paths
• Solder and rosin
• Soldering iron
• Third hand
• Pliers
• Hot glue gun

and Arduino for programming ATtiny.

Here is a schematic and design (both done in Fritzing) of my LED Dice.

Put the elements on perfboard and solder them. Next make the paths using wire and heat shrink tubing.

Remove the wires from their original locations and put them in the lower holes. Next shorten wires and cover them with solder.

Now solder the battery holders cable to perfboard. Next hot glue the board to battery case.

How to program the ATtiny you will learn from this instructable.

I prepared amazing code.

After the programming, put ATtiny to finished board. Remember to the dot next to the first pin.

The ATtiny85 LED Dice is done.

This was my first Instructable.

I'm sorry for its poor quality.
