Fulabs Electronic Hourglass DIY Kit Funny Electric Production Kits Precise With LED Lamps Double Layer PCB Board 84*40mm

Description of 5YLED Fun Electronic Hourglass Kit

1. Working Principle

   It uses an electronic circuit to control light - emitting diodes to simulate the movement of a real hourglass: the "sand grains" (lit LEDs) in the upper part fall down one by one, and the "sand grains" in the lower part pile up one by one; after the sand has run out, press the restart switch, and it will start to fall down one by one again.

2. Product Parameters and Configuration

   Hardware: Adopts high - quality 1.6mm double - sided PCB board, and 57 pieces of 5mm warm - white LEDs form the hourglass pattern; equipped with a micro switch (to adjust the speed of the hourglass), and the maximum number of lit LEDs is 28 (can be used as a decorative small night light)

Power Consumption: Controlled by a single - chip microcomputer, power consumption ≤ 0.5W, energy - saving and environmentally friendly, and supports cyclic use

   Documents: Comes with detailed assembly materials, circuit diagrams, and working principle descriptions

3. Value Highlights

   Hands - on Practice: The assembly process exercises hands - on ability and enables in - depth learning of electronic technology

Fun Expansion: It is not only an electronic production work but also can be used as a small night light for decoration, with both practicality and fun
