Waveshare 近期推出了一款专为驱动DDSM400 轮毂电机而设计的紧凑型 Raspberry Pi DDSM（直驱伺服电机）电机驱动器——DDSM Driver HAT (B)。 树莓派 HAT（Hardware Attached on Top）是一种专为树莓派设计的附加板，通过标准化的物理和电气接口来增强树莓派的功能。 直驱 ...

这是一个便携式的 IoT 显示器项目，可以基于它和 Arduino_GFX 库开发出各种实用工具。例如 WiFi 信号分析、电子相册等。配上设计良好的 3D 打印外壳，可以很方便地挂在钥匙扣或者背包上，随身携带。 参照 LCD 的 Datasheet 连接引脚。连接之前请务必通读 Datasheet ...

这是一位工程师基于硬禾学堂"暑期一起练"的ESP32-S2平台实现的网络收音机、FM收音机的功能，项目开源在电子森林的项目页面（点击左下角的“阅读原文”）。 可以通过WiFi接收网络上的电台，也可以通过FM模块接收空中的电台，并可以通过按键进行切换、选台 ...

The circuit diagram of this system represents the interconnection between the ESP32-CAM, OLED display, and rotary encoder.

Recent DIY trends show makers increasingly turning to ESP32 microcontrollers and Arduino platforms for smart home projects, replacing costlier or overpowered setups like Raspberry Pi in many cases.

It’s always nice to simulate a project before soldering a board together. Tools like QUCS run locally and work quite well for analog circuits, but can fall short with programmable logic. Tools like ...

In case you missed it, the big news is that a minimal Arduino core is up and working on the ESP32. There’s still lots left to do, but the core functionality — GPIO, UART, SPI, I2C, and WiFi — are all ...

In a significant development for the world of Internet of Things (IoT) and MicroPython, the Arduino Cloud has officially extended its support to the new Nano ESP32 board. This exciting update, which ...

This project provides a simple and practical solution using an Interactive Voice Response System (IVRS) that works completely ...

Cheap and cheerful.
