ESP8266 Tutorial

Controlling a DC motor with an ESP8266, L298N motor driver module, and Arduino Cloud provides a flexible and efficient way to automate motor control remotely. This tutorial will guide you through the setup, wiring, and code needed to achieve this.

In this tutorial, we will explore how to interface an ESP8266 with the nRF24L01 wireless module. The nRF24L01 is a low-power, 2.4GHz wireless transceiver module that is commonly used in short-range wireless communication. It communicates over SPI, while the ESP8266 is a Wi-Fi-enabled microcontroller that can be programmed using the …

I have shown how you can use ESP8266 to host a web server via HTTP and via WebSocket, use MQTT and ThingSpeak for sensor data, and even use Google Sheets. This time, I will be sharing with you how I send data between two ESP8266.

I recently bought a mini Arduino water pump that runs on 3 to 6 V. Since it consumes very little current (130 mA @ 3V according to its specs), it seems perfect to be used for small projects featuring the ESP8266. In this tutorial, I will share how I managed …

Now that you’ve set up your WeMos D1 Mini to be programmable using the Arduino IDE, it’s time to build a project. I’m a huge believer in active learning and project-making does just that. For this tutorial, I will guide you on how to build a WeMos D1 Mini WiFi …

SPIFFS or Serial Peripheral Interface Flash File System is a system that utilizes extra flash memory on the ESP8266 and ESP32 for storing files. It’s so named because the user reads, writes or deletes files in the memory using the serial interface. In this article, I will show you how …

In this article, I will guide you to the steps on how to build a WiFi servo controller project using the WeMos D1 Mini ESP8266 breakout board.

In the previous tutorial, we set up a soil moisture sensor and have its data readable via WiFi. However, that data is only accessible if the NodeMCU ESP8266 and the client (smartphone, PC, etc.) is in the same network. In this tutorial, we will use a service that allows us …

Plants need enough water to survive. But what if you forgot to water the plants? This multi-part ESP8266 tutorial aims to provide a simple soil moisture sensor that reminds you, via WiFi, that your flora needs a shower.

Relays in electronics are useful for controlling a high-power load using a smaller-power circuit. For example, an Arduino or PIC running on 5V, controlling a 240VAC light bulb, etc. This is what we have shown in our Arduino relay tutorial. But did you know that there are different types of …
