Nextion Display with Arduino – Getting Started

This post is an introduction to the Nextion display with the Arduino. We’re going to show you how to configure the display for the first time, download the needed resources, and how to integrate it with the Arduino UNO board. We’ll also make a simple graphical user interface to control the Arduino pins. Introducing theContinue reading “Nextion Display with Arduino – Getting Started”

What’s the Best LED Strip For Your Project?

LED strips are just amazing, and there are a wide variety of LED strips to chose from. Do you know what is the best LED strip for your project? Here we explain the main differences between several types of LED strips and their features. Introducing LED strips When it comes to LED strips, the mainContinue reading “What’s the Best LED Strip For Your Project?”

Guide for WS2812B Addressable RGB LED Strip with Arduino

This post is about the WS2812B LED strip, which is an addressable RGB LED strip. The information in this post also works with other similar LED strips, such as strips of the WS28XX family, Neopixel strip and others. Introducing the WS2812B LED Strip The WS2812B addressable LED strip comes in several models that differ in size, sealant or LED density. Choose the one thatContinue reading “Guide for WS2812B Addressable RGB LED Strip with Arduino”

Decoding and Encoding JSON with Arduino or ESP8266

In this blog post you’re going to learn how to decode (parse a JSON string) and encode (generate a JSON string) with the ArduinoJson library using the Arduino with the Ethernet shield. This guide also works with the ESP8266 and ESP32 Wi-Fi modules with small changes. Important: this tutorial is only compatible with the ArduinoJSON libraryContinue reading “Decoding and Encoding JSON with Arduino or ESP8266”

Flashing NodeMCU Firmware on the ESP8266 using Windows

If you’re new to the ESP8266 WiFi module, first read my Getting Started Guide with the ESP8266. You can also checkout my other tutorial on how to create a web server with an ESP8266 running NodeMCU firmware. Why flashing your ESP8266 module with NodeMCU? NodeMCU is a firmware that allows you to program the ESP8266 modules with LUA script. And you’llContinue reading “Flashing NodeMCU Firmware on the ESP8266 using Windows”

Guide for TCS230/TCS3200 Color Sensor with Arduino

This post shows you how to detect colors with the Arduino using the TCS230/TCS3200 color sensor. The TCS3200 color sensor can detect a wide variety of colors based on their wavelength. This sensor is specially useful for color recognition projects such as color matching, color sorting, test strip reading and much more. Introduction The TCS3200 color sensor –Continue reading “Guide for TCS230/TCS3200 Color Sensor with Arduino”

Guide to SD Card Module with Arduino

In this post we’re going to show you how to use an SD card module with Arduino to read and write files on an SD card. For an Arduino project with the SD card module read our blog post: Arduino temperature data logger with SD card. Introducing the SD Card module The SD card module isContinue reading “Guide to SD Card Module with Arduino”

Arduino – Ultrasonic Sensor with LEDs and buzzer

Hi guys, This is my first tutorial,  I’ve just started a few months ago learning electronics (previously I’ve just knew how to program in C and Python). When I finished this project (took me about 5 hours or something) I’ve decided to share to help anyone that is starting in electronics. What’s this project about? Basically weContinue reading “Arduino – Ultrasonic Sensor with LEDs and buzzer”

Arduino with PIR Motion Sensor

In this project you’re going to create a simple circuit with an Arduino and PIR motion sensor that can detect movement. An LED will light up when movement is detected. Introducing the PIR Motion Sensor The PIR motion sensor is ideal to detect movement. PIR stand for “Passive Infrared”. Basically, the PIR motion sensor measures infrared lightContinue reading “Arduino with PIR Motion Sensor”

Nextion Display with ESP8266 – Touchscreen User Interface for Node-RED

This project shows how you can build a touchscreen user interface for Node-RED with the Nextion display and the ESP8266 to control your electronics appliances. The aim of this project is being able to control your home automation system through the Nextion display without the need to go to your smartphone or your computer to accessContinue reading “Nextion Display with ESP8266 – Touchscreen User Interface for Node-RED”
