The table shows the pin configuration of the Arduino UNO–based robotic arm. The red (VCC) wires of all servos are connected ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

Apple had a lot to say about its new phones during the “Awe Dropping” event Tuesday, but there were plenty of little features that couldn’t fit in the keynote. One interesting feature spotted in the ...

The iPhone 17 models include an Accessibility setting to disable pulse width modulation (PWM), according to information found in the iOS 26 release candidate. There will be a toggle located in 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 ...

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 ...

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 ...

基于开源控制平台 Arduino 控制器的开放性与易用性，在原有的电子技术综合实验中新增了以 Arduino 单片机为核心的实验教学模块。利用 Arduino 单片机中的脉冲宽度调制技术（PWM技术），单片机根据接收到的红外信号对应调节两个直流电机的输入电压，从而控制其 ...

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 ...

37款传感器与执行器的提法，在网络上广泛流传，其实Arduino能够兼容的传感器模块肯定是不止这37种的。鉴于本人手头积累了一些传感器和执行器模块，依照实践出真知（一定要动手做）的理念，以学习和交流为目的，这里准备逐一动手尝试系列实验，不管成功 ...
