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 ...

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 ...

From a simple electronic toothbrush to complicated robotics systems, DC motors are present everywhere. In most of our previous Arduino projects, we have used these DC motors as actuators and ...

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 ...

How to use compiler optimization options with the Arduino IDE. The goal of Arduino is to make microcontroller development as easy as possible so that the programmer can concentrate on his or her goals ...

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 ...
