A cartridge-based console project that blends Arduino fundamentals, retro gaming nostalgia, and modern maker tools.

Magnets keep strings suspended without anchor points, and pushing a magnet piece bends notes, so you get expressive sounds with simple moves.

Abstract: The main objectives in driving multiple LED strings include achieving uniform current control and high-performance pulse width modulation (PWM) dimming for all strings. This study proposes a ...

当环境光线变亮时，又自动关闭灯带。 连接 Arduino ↔ LDR 分压 ↔ 继电器模块 ↔ 12V 灯带。 热熔胶枪（可选） 用于固定 LDR 位置或整理线材，提升结构可靠性。 A0 点的电压随光照变化而变化，Arduino 通过 analogRead(A0) 读到 0–1023 之间的数值，即可反映当前亮度。
