How to Build a Digital Dice
Create your own digital dice with this step-by-step guide, using LEDs to display random numbers from 1 to 6. Includes materials, interactive instructions, video tutorials, troubleshooting tips, customization ideas, and a project gallery.
Project Outcome
By completing this project, you’ll build a fully functional digital dice that generates random numbers (1 to 6) when a button is pressed, displayed through LED patterns. Controlled by an Arduino, this project introduces digital input handling, LED control, and random number programming.
- Build Skills: Master button input, LED wiring, and Arduino programming.
- Customize: Add features like sound effects, LED animations, or an OLED display.
- Learn: Gain hands-on experience in electronics and random number generation.
Perfect for beginners and hobbyists interested in interactive electronics!

Troubleshooting Tips
Push Button Not Detecting
Check button wiring, ensure proper pull-down resistor, and verify pin assignments in code.
LEDs Not Lighting Up
Confirm LED polarity, resistor values, and correct Arduino pin assignments.
Inconsistent Numbers
Ensure random seed initialization in code and check for button debounce issues.
No Output on Press
Verify power supply stability and check code for proper button interrupt handling.
