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 ...

L298N，是一款接受高电压的电机驱动器，直流电机和步进电机都可以驱动。在5V到35V的电压范围内，提供2安培的电流，并且 ...

We just got our hands on some engineering pre-samples of the ESP32-C3 chip and modules, and there’s a lot to like about this chip. The question is what should you compare this to; is it more an ESP32 ...

These days, everything’s got a clock in it, and a good proportion of those clocks are automatically syncronized to high-accuracy Internet time servers. Back in the past, things weren’t so easy. Often, ...

Operating systems come in all kinds of shapes and sizes, and just a few decades ago, it wasn't uncommon to run an operating system on a computer with a clock speed of a few hundred megahertz paired ...
