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 ...

This repository contains a program to calibrate a 3.5" touch screen display shield, as shown below - Most 3.5" TFT LCD Touch displays use the ILI9486 Display Driver and include a resistive touchscreen ...

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 ...

The ESP32-2424S012 is an ESP32-C3 WiFi and BLE development board with a 1.28-inch round touchscreen color display that is fully housed in a black or white plastic enclosure and suitable for Arduino ...

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。
