Description
Fun electronic hourglass production parts. Using a 1.6mm double-sided PCB board, the circuit is composed of 57 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 above can adjust the speed of the hourglass and light the LED at the same time. There are 28 in number, which can be used as a decorative night light. The power consumption is only tens of milliamperes, which is less than 0.5W, which is environmentally friendly and energy-saving. The assembly process can greatly exercise your hands-on ability and cultivate your interest in learning electronic technology.
Warm reminder: The shipment is in loose parts, you need to assemble it by yourself!
Principle
The electronic hourglass uses light-emitting diodes controlled by an electronic circuit to represent sand particles, simulating the movement process of the hourglass. The electronic hourglass will be like a needle-shaped hourglass. The upper sand particles (lighted light-emitting diodes = pole tubes) fall down one by one, and the lower sand piles up one by one. After the leak is over, press the restart switch once, and it will start to leak again one by one.
