额……老铁们，我老鼓捣单片机的了。今天简单谈下一个Arduino开发板一个非常初级的问题——如何点亮板载LED灯实现呼吸灯 ...

Hello Hackers! Today we have a really interesting topic. Searching the internet, I didn't find any simple solution on "How to read data from car parking sensors," so I decided to write a short and ...

警告！！ 本项目中讨论的电路图仅用于教育目的。请注意，使用 220V 交流电源电压需要采取极端的预防措施，并应遵循安全程序。电路运行时，请勿触摸任何元件或电线。 就像我们在许多基于 Arduino 的家庭自动化项目中所做的那样，使用开关或使用某种控制 ...

For years, there has been a clear distinction between the Arduino and Raspberry Pi boards. There are some things the Arduino can do that the Raspberry Pi can't, and vice versa. When you think of ...

Among all the Arduino boards, the Uno is most folks' go-to choice, and for good reason. It's the perfect platform to get started with Arduino, it's capable enough to handle a wide range of tasks, and ...

The purpose of this project is to provide a 4-20 mA output from a PWM signal generated by a microcontroller. One of the more interesting applications of this circuit would be to replace or to realize ...

Abstract: This paper presents a simulation of a buck converter using pulse-width modulation (PWM) signal frequencies and duty cycles generated by an Arduino microcontroller for solar panel application ...

What is PWM? PWM is a technique by using we can control the voltage or power. To understand it more simply, if you are applying 5 volt for driving a motor then motor will moving with some speed, now ...
