Electronic Hourglass Kit Soldering Kit

Descriptions

 

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 LEDs (light-emitting diodes)  in the upper part of the kit will drop down 1 by 1 to the lower part as a real hourglass does with sand.

Then with a click of the switch start all over again

The kit uses a high-quality 1.6mm double-sided PCB board, the circuit consists of 57 pieces of warm white LED, under the control of the microcontroller program, showing the effect of a simulated hourglass, the above microswitch 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. The assembly process can greatly exercise your hands-on ability to cultivate an interest in learning electronics.

Feature: 1. Board Size：84*40mm 2. Power Supply Voltage：5V
