Kitten Guitar Water Lamp

Design the circuit and PCB schematic diagram on Lichuang EDA. Pay attention to the circuit wiring during design. The wiring patterns are neat and tidy. Through NE555 and CD4017, an interesting effect can be achieved that does not require programming and can be achieved by relying only on the circuit. By powering the NE555, it can continuously send out a square wave pulse signal, and input this signal into CD4017. CD4017 is a decimal counter, so when it receives the pulse signal, it will output high power from 0 to 9 in sequence. level, then it will start again to control the blinking of the LED. Through the potentiometer, changing the ratio of the two resistors changes the charging and discharging time ratio of the capacitor, thereby controlling the frequency of LED flashing.

In this activity, I learned and mastered how to use Easy EDA. The EDA web design editor is very convenient to use and easy to use. The design interface is simple and easy to understand. I also learned the corresponding circuit principles and designed an interesting small item.

The problem I encountered during the actual production process was that I was not skilled in welding and some problems occurred. At the same time, I paid attention to the welding of the positive and negative poles of the electrical components and whether the components were placed in the opposite direction. With the help of my seniors, I slowly Try, gradually become proficient, and complete the production. When you turn on the power and see the running lights lighting up one by one, you will feel a sense of accomplishment and will be confident in future design and production.
