Combining it with the BME280 temperature sensor can provide you with accurate temperature, humidity, and pressure readings. In this guide, we’ll walk you through the process of connecting the BME280 sensor to the Wemos D1 Mini and displaying

The AHT10 temperature sensor is a high-precision digital sensor that provides accurate temperature and humidity readings. In this tutorial, we’ll guide you through the process of connecting the AHT10 sensor to the Wemos D1 Mini, a popular ESP8266-based development board, and displaying the sensor data on the Serial Monitor using the Arduino IDE. Materials Needed:

Are you looking to monitor temperature and humidity using a WeMos D1 Mini? The DHT22 sensor is a great choice for such projects because of its digital reliability and precision. In this blog post, we’re going to walk through the steps of connecting the DHT22 sensor to a WeMos D1 Mini and output the sensor

In this tutorial, we will guide you through the process of connecting an OLED display and a KY-040 rotary encoder to a Wemos D1 Mini. The objective is to create a countdown timer using the provided Arduino IDE code. The countdown timer will be displayed on the OLED screen, and the timer duration can be

In this tutorial, we will explore how to connect and use an OLED display with the Wemos D1 Mini, a popular ESP8266-based development board. OLED (Organic Light Emitting Diode) displays are known for their vibrant colors and sharp contrast, making them an excellent choice for various projects. For this tutorial, we’ll be using the U8g2

RS485 communication is a widely used standard for serial communication in industrial and automation applications. In this tutorial, we will demonstrate how to establish RS485 communication between two Wemos D1 Mini boards. One board will act as the sender, and the other as the receiver. When a button is pressed on the sender board, it

In this tutorial, we will learn how to send a string from one ESP8266 to another using an RS485 serial communication module. The ESP8266 is a popular microcontroller board that can be used for various IoT projects, and RS485 is a robust communication protocol often used for longer-distance communication between devices. We will have a
