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.

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
Weave Radial Spokes
Thread conductive yarn from the center hub to 8 outer frame pins to form 8 radial spokes.
Weave Concentric Spiral Circles
Weave concentric spiral circles connecting the spokes to complete the spider web geometry.
Place Toy Spider on Web
Move the toy spider along different threads of the web.
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.
