it’s great for a quick-and-dirty circuit diagrams. Not exactly schematics, but [Duckman] has some Arduino pinout diagrams he made using ASCII-art. These could be useful when pasted into source ...

To start and operate the weather monitor, just connect display to ESP32. Connecting all other modules is optional. Instead of schematic diagrams, I post half-drawings, half-photos, so that it is clear ...

Wokwi is an online simulator for Arduino, Raspberry Pi Pico, and ESP32 boards, or even your own custom microcontroller ... GND, and so on, and the diagram can also be seen in the source code as a JSON ...

The schematic for the Arduino and ESP32 Based Efficiency Meter is shown below. Creating this circuit is very simple and uses generic components. The operation of the circuit is very simple. We will be ...

Bojan Jurca’s open-source Arduino sketch "Esp32_oscilloscope," transforms any ESP32 board to function as a web-based oscilloscope accessible over WiFi. While the Scoppy project demonstrated the ...

This repository is deprecated. The BLE code is now part of the ESP32 Arduino core, making it automatically available to any Arduino ESP32 project without the need for manual import. For more ...

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 ...

Details on the Arduino Cinque are slim at the moment, but from what we’ve seen so far, the Cinque is an impressively powerful board featuring the RISC-V FE310 SoC from SiFive, an ESP32 ...
