an electronic hourglass

Abstract

The invention discloses an electronic hourglass, which comprises a single-chip microcomputer, a USB interface connected with the single-chip microcomputer, and an LED lamp connected with the single-chip microcomputer. The USB interface is connected with a voltage-stabilizing protector, and an external power supply is used as a charging input terminal through the USB interface and the voltage-stabilizing protector. Charging the external rechargeable battery, the signal of the real-time charging amount of the rechargeable battery by the external power supply is sent to the single-chip microcomputer in real time through the USB interface, the single-chip microcomputer recognizes and judges according to the built-in program, and controls the corresponding number of LED lights to display; and is triggered by the LED light graphic switching switch The single-chip microcomputer makes its built-in program control and display multiple Logo graphics. In addition to the timing function, the present invention can also display the animation display of the real-time charging capacity of the external rechargeable battery, and the LED lamp group simulates an hourglass and quicksand, and dynamically displays multiple Logo graphics.

Description

technical field [0001] The invention relates to the technical field of daily necessities, in particular to an electronic hourglass. Background technique [0002] The hourglass is a small and lovely timer, which is often given as a small gift and is very popular among young people. However, this traditional hourglass has its own limitations, such as the timing cannot be adjusted, the dynamic effect cannot be seen at night, and it has no other use except timing. This patent will use LED lights to simulate an hourglass. In addition, it can also display an animation display of the real-time charging capacity of an external rechargeable battery, and dynamically display multiple Logo graphics, which is full of creativity. Contents of the invention [0003] The invention provides an electronic hourglass, which can display real-time charging amount animation, and utilize LED lights to turn on and off to simulate the hourglass quicksand. A further purpose is to dynamically displa...
