šćLED Hourglass That can Flowć:The electronic hourglass uses light-emitting diodes controlled by electronic circuits to represent sand grains, simulating the movement process of the hourglass.
ā”ćSupply voltageć:5V (DC power supply)
šÆćCircuit principle and introduction of key componentsć:
šÆć1ć:The circuit is composed of 57 3mm blue 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. The number of LEDs lit at the same time is 28, which can be used as decoration. The power consumption of the night light is only tens of milliamps, less than 0.5W, which can be described as environmental protection and energy saving.
šćDIY Soldering Kitć: It is widely used in schools to help students learn basic mechanical and electronic skills.There are many life scenarios for this circuit application, and it is a kind of circuit that circuit designers need to master.
šćEasy Assemblyć: The connection that was clearly mapped and labeled on the board makes it easy to assemble. Even beginners can easily solder successfully.
šćWholesale businessć:We have been engaged in the wholesale and retail business of electronic related products for a long time. Welcome letter to discuss wholesale business. The larger the amount, the better the price.
