KIT - 25m Copper Tapes & LEDs (100 Red, 100 Green, 100 Blue)

Overview

A raw-materials bundle for paper circuits and creative electronics — two rolls of conductive copper tape plus 300 diffused 5mm LEDs (100 each of red, green, and blue), enough for multiple builds.

How It Works

1. Copper tape is laid down on paper or card to form a circuit path — conductive on both the tape surface and adhesive.
2. An LED is placed across a gap in the tape, long lead (+) toward the positive side.
3. A coin-cell battery (not included) completes the circuit and lights the LED.

FAQ

Do I need coding experience? No prior experience is required — this kit is built around one specific project, and the full code is freely available. A build guide will be linked here once published.

What tools do I need beyond what's included? A computer with the free Arduino IDE (or ESP32/ESP8266 board support, where applicable) installed to upload the code. No soldering is required for this build.

Can I reuse the parts afterward? Yes — every component in this kit is a standard, reusable part you can use in future projects, not a single-use kit.
