LED lamp electronic hourglass kit welding practice/fun DIY electronic production/STC15W201S single chip microcomputer -63913
product detail
Description:
Electronic hourglass with electronic circuit control of the light-emitting diodes that sand, mimicking the movement of the hourglass. The electronic hourglass will be like a real hourglass, the upper part of the sand (light-emitting diodes) one by one down, the lower part of the sand a pile of pile up. After the leak, will restart the switch click, will start a grain of a drop down.
Using high-quality 1.6mm double-sided PCB board, the circuit consists of 57 5mm warm white LED composition of the hourglass pattern, under the control of the microcontroller program, showing the effect of simulated hourglass, the above micro switch can debug hourglass speed, while lit LED number 28, can be used as a decorative night light, power consumption only tens of milliamperes, less than 0.5W, can be described as environmental protection and energy saving.
