This topic is the design and manufacture of electronic hourglass, using a LED light out to simulate the movement process of ancient hourglass timing.
Electronic hourglass in an electronic circuit control of sand, sand LED said the movement process simulation. Like the hourglass of electronic real hourglass - first, is located in DaoSanJiao above 15 LED light (the full container), the simulation of sand located within the triangle and pour over the grains of light (LED) to extinguish a triangle next founder, within a LED and position correspond to simulate the real (as the sand, sand, a grain by a grain of falling sand bottom, a grain by a grain heap up). Until the end of the above all, LED the LED on below, after all, is below LED light above all, and repeat the process. The whole design is used as the main control chip 74HC164 displacement registers, adopts chip TC4093 proced more harmonic oscillator gate constitute the clock signal.
This paper mainly introces the working principle of the electronic hourglass and circuit structure.
