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.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Materials
- 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
- 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.
