It's amazing what you can do with an ESP32 (or two).

This document is aimed at the Arduino developers, radio experimenters, hobbyists and anyone interested in building a receiver based on the Si473X IC family from Silicon Labs. This project is about an ...

The BK1088E is a single-chip solution for receiving AM, FM, and shortwave radio. Using inexpensive components (Arduino Pro Mini, some push buttons, and a standard OLED or TFT display), the hobbyists ...

Waveshare has introduced the ESP32-C6-LCD-1.47 development board powered by an ESP32-C6 RISC-V microcontroller with WiFi 6 and Bluetooth 5 connectivity and equipped with a 1.47-inch display with a ...

The Arduino Opta micro programmable logic controller (PLC) provides a unique entry point into the automation field. Automation fields like smart homes, process controls, and robotics are project areas ...

We always look at the round LCDs and wonder what to do with them other than, of course, a clock. Well, [shabaz] had a great idea: use it as a star map display. The ...

With technology advancing at an ever-accelerating rate, the gadgets and innovations you come across daily can often feel like they've jumped straight out of a science fiction movie. For instance, you ...

Hello, I’m excited to review the ESP32 display modules and HMI touchscreens from Elecrow with sizes ranging from 2.4 to 7.0 inches. For this review, Elecrow kindly provided me with both 3.5-inch and 7 ...

项目介绍了如何使用STM32微控制器（在Arduino IDE中）制作一个简单的500MHz示波器。与之前使用Arduino制作的最大频率仅为50kHz的示波器相比，STM32版本性能更好且成本更低。STM32是STMicroelectronics开发的32位ARM微控制器，可以安装Arduino引导加载程序并用作标准Arduino。
