The Electronic hourglass diy kit, using 1.6mm double-sided PCB board, the circuit is composed of 57 pieces of 5MM warm white LEDs to form an hourglass pattern, under the control of the microcontroller program, it presents the effect of simulating an hourglass. The micro switch on it can adjust the speed of the hourglass, and at the same time The number of lit LEDs is 28, which can be used as a decorative night light. The power consumption is only tens of milliamperes, less than 0.5w, which can be said to be environmentally friendly and energy-saving. The assembly process can greatly exercise your hands-on ability and cultivate your interest in learning electronic technology. Product parameters: Product Name: Electronic Hourglass Kit LED color: 5MM warm white Power supply mode: 5V Product size: 84*39mm The electronic hourglass uses light-emitting diodes controlled by electronic circuits to represent sand grains, simulating the movement process of the hourglass. The electronic hourglass will be like a needle-shaped hourglass, the upper sand grains (lighted LEDs) will fall down one by one, and the lower sand grains will pile up one by one. After leaking, press the restart switch once, and it will start to leak one by one again. Features: 1. Accessories quality assurance and long life. 2. The principle is simple and the assembly is convenient. 3. Seiko production, stable performance. 4. Insulated and flame retardant, safe to use. 5. Wide application and strong interest.
