This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...

Here is a simple Arduino Camping Light project. In this design, only one push button switch is used to control the light output (from a bunch of white LEDs) between off, dim, medium, and full ...

本项目将在Arduino IDE环境下，利用ESP32产生的PWM信号控制多个LED。项目所需物料如下： ESP32带一个包含16通道LED PWM控制器，可配置以产生不同特性的PWM信号。项目开始之前需要先安装Arduino IDE，连接妥当后就可以把ESP32 DOIT DEVKIT V1板用作LED PWM控制器了。 使用Arduino ...

In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is ...

[Alan] was commissioned to make some wearable, radio-controlled LED strips for the Travelling Light Circus. It has taken some time, but he has recently finished some prototypes, and thought it was a ...
