ESP8266 Tutorial

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 and the client (smartphone, PC, etc.) is in the same network. In this tutorial, we will use a service that allows us to …

Plants need enough water to survive. But what if you forgot to water the plants? This multi-part 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 shown in our Arduino relay tutorial. But did you know that there are different types of relay? …

Last time, I featured the 0.96” OLED display and how to use with an Arduino microcontroller. If that screen was too small, you can try upgrading to a slightly larger 1.3” display. This tutorial aims to guide you on how to use the 1.3” OLED with popular microcontroller boards such …

The WeMos D1 Mini is part of the WeMos D1 family of development boards that feature the popular ESP8266 WiFi chip. If you have just purchased this board, then you’re on the right page. This WeMos D1 Mini tutorial will show how to start programming with this device.

The DHT22 is a temperature and humidity sensor in one package. It is widely used mainly due to its price but also because of it being robust and user-friendly. In this NodeMCU DHT22 interfacing tutorial, I will guide you in creating an IoT-based weather monitoring project.
