In this project, we simulate a die using a touch sensor. Every time the touch sensor is tapped, a random number between 1 and 6 is generated and displayed on the 7-Segment LED.

The core of the program is the randomSeed(), which is initialized with a random input from analogRead() on an unconnected pin.

As a fun feature, a pattern generator is included for every "roll" of the die!

Electronic Die using Touch Sensor and Arduino

EXPANDED TECHNICAL DETAILS

Random Number Generation

This electronic die recreates the physical act of rolling dice using motion sensing.

  • Triggering: A Tilt Sensor (mercury or ball-roll) detects the "Shake" gesture. When shaken, the Arduino enters a high-speed random loop.
  • Seed Logic: Uses the random() function, seeded by the noise on an unconnected analog pin to ensure true unpredictability.

Visual Output

  • Display: The result (1-6) is shown on a Large 7-Segment LED Display. The Arduino handles the common-cathode or common-anode logic to illuminate the correct segments.
  • Persistence of Vision: While "rolling," the display flashes rapidly to simulate uncertainty before coming to a stop on the final digit, accompanied by a short beep for effect.
