In this guide, you’ll learn how to use the RCWL-0516 Microwave Radar Proximity sensor to detect motion with the ESP8266 NodeMCU. We’ll show you how to wire the sensor to the ESP8266 board and we’ll write an Arduino sketch to detect when motion is detected. The RCWL-0516 is a great alternative to the popular PIR motion sensor.

In this guide, you’ll learn how to control a stepper motor with the ESP8266 NodeMCU board. We’ll use the 28BYJ-48 unipolar stepper motor with the ULN2003 motor driver. We’ll program the ESP8266 board using Arduino IDE.

The BME680 is an environmental digital sensor that measures gas, pressure, humidity and temperature. In this guide you’ll learn how to use the BME680 sensor module with the ESP8266 NodeMCU board using Arduino IDE. The sensor communicates with a microcontroller using I2C or SPI communication protocols.

This tutorial shows how to send notifications to your Telegram account when the ESP826 NodeMCU detects motion. As long as you have access to the internet in your smartphone, you’ll be notified no matter where you are. The ESP board will be programmed using Arduino IDE.

In this getting started guide you’ll learn how to read digital inputs like a button switch and control digital outputs like an LED using the ESP8266 NodeMCU board with Arduino IDE.

There is a wide variety of sensors, modules, and peripherals compatible with the ESP8266 NodeMCU boards. We have tutorials for the most popular components. This article is a compilation of 20 free guides for ESP8266 sensors and modules. Most guides cover programming the ESP8266 using the Arduino core, but we also have tutorials for MicroPython.

The BMP388 is a tiny and precise absolute barometric pressure sensor. Because of its precision, it is often used to estimate altitude in drone applications. It can also be used in indoor/outdoor navigation, GPS applications, and others. In this tutorial, you’ll learn how to use the BMP388 pressure sensor with the Arduino board—we’ll show the wiring diagram and an example code.

There is a new Arduino IDE—Arduino IDE 2.0 (beta version). In this tutorial, you’ll learn how to install the ESP8266 boards in Arduino IDE 2.0 and upload code to the board. This tutorial is compatible with Windows, Mac OS X, and Linux operating systems.

This tutorial shows how to set a static/fixed IP address for your ESP8266 NodeMCU board. If you’re running a web server or Wi-Fi client with your ESP8266 and every time you restart your board, it has a new IP address, you can follow this tutorial to assign a static/fixed IP address.

In this tutorial you’ll learn how to get date and time from an NTP server using the ESP8266 NodeMCU with Arduino IDE. Getting date and time is useful in data logging projects to timestamp readings. To get time from an NTP Server, the ESP8266 needs to have an Internet connection and you don’t need additional hardware (like an RTC clock).
