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 ...

This project presents the design and implementation of a dual-fan PWM cooling circuit, integrating a compact and efficient power supply with intelligent fan speed regulation. This project presents the ...

本文讲述了使用Arduino IDE对RP2040进行编程时，GPIO与pinMode的对应关系，和使用PWM功能时的注意点。 需注意函数pinMode的入参序号与实际GPIO不对应；需注意通过函数analogWrite最多输出16种PWM占空比，且周期均为2ms。 上一贴说到RP2040在Arduino Nano上的GPIO分布： 【Follow me ...

In exploring the use of analogWrite() and digitalWrite() on the Raspberry Pi Pico using Arduino, I have discovered some strange behaviors when switching between those modes on the same GPIO pin. This ...

This article is for those who are interested in learning about the fundamentals of DC motor control in electronic systems. The most prevalent form of the motor is a direct current (DC). There is ...

Since Arduino plans to launch its own Raspberry Pi RP2040 based board with Arduino Nano RP2040 Connect, one would have expected software support for the Arduino IDE would have come from the company ...

Using pulse-width modulation (PWM), we can apply the average voltage value to our device, adjusting its value by turning the signal on and off at high speed. The duty cycle is defined as the amount of ...
