Pattern Around Us (Smart Fibonacci & Growing Sequence LED Matrix)

Source:

Explore growing number patterns (2, 4, 8, 16... / 1, 1, 2, 3, 5, 8...) on a 64-LED NeoPixel matrix. Children key in missing numbers in sequence puzzles; correct inputs trigger animated LED spiral growth patterns.

Categorisation

Props & Materials Required

  • •8x8 WS2812B NeoPixel RGB LED matrix panel
  • •4x4 keypad module
  • •ESP32 controller board
  • •0.96-inch OLED display screen
  • •DFPlayer Mini MP3 module + 3W speaker

Step-by-Step Instructions

1

Select Pattern Type

Select pattern: 'Fibonacci Sequence (1, 1, 2, 3, 5, 8, 13, 21)'.

2

Solve Missing Sequence Number

OLED displays: '1, 1, 2, 3, 5, 8, 13, [ ? ]'. Timer ticks down.

3

Type Missing Term

Child calculates 8 + 13 = 21 and types '21' on keypad.

4

Watch Golden Spiral LED Animation

If correct — NeoPixel 8x8 matrix illuminates a glowing Golden Spiral pattern! Speaker narrates: 'Correct! Fibonacci numbers appear in sunflower seeds and pinecones!'

Why It Works & Notes

Mathematical patterns (Fibonacci sequence in pinecones/sunflowers, doubling sequences) form the foundation of algebraic thinking. Visualizing sequence growth as expanding LED spirals makes abstract number series tangible.
