Web Weaving & Geometrical Net Builder

Source:

Construct a spider web out of conductive yarn thread attached to a wooden frame. Touch sensors detect which radial spoke or concentric circle thread a toy spider touches, playing authentic spider web facts.

Categorisation

Props & Materials Required

  • Wooden circular web frame
  • Conductive stainless steel yarn / thread
  • MPR121 capacitive touch sensor board
  • Toy spider with metal touch leg
  • ESP32 controller board
  • 0.96-inch OLED display screen
  • DFPlayer Mini MP3 module + 3W speaker

Step-by-Step Instructions

1

Weave Radial Spokes

Thread conductive yarn from the center hub to 8 outer frame pins to form 8 radial spokes.

2

Weave Concentric Spiral Circles

Weave concentric spiral circles connecting the spokes to complete the spider web geometry.

3

Place Toy Spider on Web

Move the toy spider along different threads of the web.

4

Capacitive Touch Audio Fact

When spider touches a thread, MPR121 sensor detects touch. Speaker announces: 'Spoke 3 touched! Spider silk is 5 times stronger than steel of the same thickness!'

Why It Works & Notes

Spider webs are natural masterpieces of geometry and physics (radial spokes + concentric spiral circles). Weaving a web with conductive yarn turns a bio-geometry art activity into a multi-point touch sensor grid.
