This system uses a colour-changing LED (RGB LED/tri-colour LED) that switches to a new colour every 5 seconds. Simultaneously, the colour name is displayed on an OLED mini screen (SSD1306). This ...

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 ...

PWM techniques control power delivery in electronic devices by varying the duty cycle, which is the ratio of “on” time to the total period of a periodic signal. As shown in Figure 1, precisely ...

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 ...

So you finally decided to hop on the Arduino bandwagon and start making electronic projects as a fun hobby. As a beginner getting started with Arduino, your first instinct is typically to buy a ...

A Microchip Technology PIC microcontroller can be an accurate solution for calculating the timing of a pulse-width modulation (PWM) signal due to its architecture. With this design, you can measure ...
