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.

Step 1: Materials

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.

Step 2: Schematic and Design

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

Step 3: Soldering Time!

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

Step 4: Prepare Battery Holder

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

Step 5: End of Soldering.

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

Step 6: Program the ATtiny Using Arduino

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.

Step 7: Done

The ATtiny85 LED Dice is done.

This was my first Instructable.

I'm sorry for its poor quality.
