Aideepen | DC5V Electronic Hourglass DIY Kit with LED Light Double-layer PCB Board DIY Soldering Assembly Parts with DC Power Cord

Features:1. Individual LED sand grains cascade down layer by layer, creating a lifelike hourglass visual effect2. Double-layered reinforced circuit board ensures stable, reliable soldering for a professional DIY experience3. Knob freely adjusts sand flow speed, letting you control interactive fun at will4. Ultra-low power consumption under 0.5W, DC 5V power supply, energy-efficient continuous operation5. Serves as nighttime ambient lighting—28 steady LEDs create a serene aesthetic atmosphereProduct Specifications:Product Name: Electronic Hourglass KitOperating Voltage: DC 5VPower Consumption: PCB Dimensions: 39*79mmInterface: DC PortLED Color: BlueDescription:The electronic hourglass uses electronically controlled LEDs to simulate the movement of sand grains within a traditional hourglass. Like a traditional hourglass, the upper grains (illuminated LEDs) trickle down one by one while the lower grains accumulate. After completion, pressing the reset switch initiates a new cycle.This 57-LED electronic hourglass kit features premium 1.66mm double-sided PCB boards. The circuit features 57 blue 3mm LEDs arranged in an hourglass pattern. Controlled by a microcontroller program, it simulates the hourglass effect. The top microswitch adjusts the sandfall speed. With 28 illuminated LEDs, it doubles as a decorative night light, consuming only tens of milliamps (less than 0.5W) for eco-friendly energy efficiency. Assembly enhances hands-on skills and fosters interest in electronics.Shipping Contents:Kit x1Power Cable x1
