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 ...
It all started when [Damien Walsh] got his hands on some surplus LED boards. Each panel contained 100 mini-PCBs hosting a single bright LED that were meant to be to be snapped apart as needed. [Damien ...
[Stefan Schüller] was a fan of the LED signs that display arrival information for the trams and buses in their city of Zürich. [Stefan] was having trouble finding a source to purchase the signs so, ...
Open-hardware platforms enable rapid prototyping and faster time-to-market of new IoT applications. The objective of this post is to give a brief introduction to another open-hardware IoT playground — ...
ESP32是体积小巧却功能强大的微控制器,能够完成各种惊人的任务。其中最有力的应用之一是TinyML——一种轻量级机器学习框架,可用于构建异常检测、音频识别或图像分类等功能。图像分类举例来说非常容易,我只用了五分钟就完成了二元分类的搭建。二元分类是一 ...
