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.

<p>very nice work keeping it sleek and simple. you should try to design a 3D printed cover for it. and then sell them online as electronic dice systems :)<br>.<br>check this out, it may give you ideas; <a href="https://www.instructables.com/id/Custom-arduino-parts/" rel="nofollow">https://www.instructables.com/id/Custom-arduino-par...</a></p><p>.<br>welcome to the community.!</p>
<p>I'd like make a PCB and sell them as kit for self-assembly. 3D printing is too expensive for it...</p>
<p>I don't know what you are talking about, this is an excellent first instructable! Thanks for sharing and being a part of the community!</p>
<p>Thanks, I don't think so, because I am not Englishman, I'm from Poland.</p>
