@antinkramer: Built a smart gesture-controlled desk lamp using Arduino Nano + ultrasonic sensor ✨ The lamp reacts to hand distance and dynamically changes the light length along the vertical LED bar. Hold your hand at a certain height for a second — the lamp remembers the level and keeps glowing there. In this prototype I used: • Arduino Nano • HC-SR04 ultrasonic sensor • LEDs with resistors • Custom LED control • Hand soldering + DIY assembly Wanted to create something minimal, interactive and futuristic while still easy to build at home ⚡
