Connect the ESP-01 module using a cross connection: ESP-01 TX → Arduino UNO RX; ESP-01 RX → Arduino UNO TX; Ensure proper voltage levels (ESP-01 operates at 3.3V). Using Digital Pins with a Library.

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 … ...

This project brings support for the ESP8266 chip to the Arduino environment. It lets you write sketches, using familiar Arduino functions and libraries, and run them directly on ESP8266, with no ...

The ESP8266-01 has only 2 or 3 GPIO, none of whom are analog ones ... but in general, yes. I’ll bet the Arduino DHT library works just fine on the ESP8266 without any major modifications. Report ...

Some of the newer Espressif Systems wireless SoCs such as the ESP32-H2 and ESP32-C6 support Zigbee through their built-in 802.15.4 radio. It’s been working since the release of the ESP-IDF 5.1 ...

Arduino has introduced a Nano shaped board with a Wi-Fi and Bluetooth LE capable Espressif’s ESP32-S3 microcontroller, supporting it with the Arduino IDE and MicroPython. “Beginners can explore in an ...
