Everything you need to know about Internet of Things. What is Internet of Things(IoT)? Internet of Things,or Iot refers to the ability of performing particular task on electronic device (sensor) using internet when it is connected.It also refer to the ability  to transfer data over a network without requiring human-to-human interaction. The Internet of ThingsContinue reading “What is IoT?”

In this project you’re going to build an Android app to control the color of an RGB LED with a smartphone via Bluetooth. You’re going to build the Android app using a free web based software called MIT App Inventor 2. This is a great project to learn how to interface the Arduino with aContinue reading “Android App – RGB LED with Arduino and Bluetooth.”

In this project, you’re going to build a web server with an ESP8266 to remotely control an RGB LED. This project is called ESP8266 RGB Color Picker. To learn more about the ESP8266 and RGB LEDs use the following tutorials as a reference: How do RGB LEDs work? Getting started with the ESP8266 ESP8266 web server withContinue reading “ESP8266 RGB Color Picker”

TIn this project, I’ll show you how you can build your own mood light. You’ll use an ESP8266 to remotely control the color of your light using your smartphone or any other device that has a browser. This project is called $10 DIY WiFi RGB LED Mood Light. To learn more about the ESP8266 and RGB LEDsContinue reading “$10 DIY WiFi RGB LED Mood Light with ESP8266 (Step by Step)”

This post is about how to use the DS1307 Real Time Clock (RTC) module with the Arduino. You can also follow this guide for other similar modules like the DS3231 RTC. Introducing the Real Time Clock module The real time clock module is the one in the figure below (front and back view). When you firstContinue reading “Guide for Real Time Clock (RTC) Module with Arduino (DS1307 and DS3231)”

This post shows you how to create a temperature Arduino data logger. We’ll use the DHT11 to measure temperature, the real time clock (RTC) module to take time stamps and the SD card module to save the data on the SD card. Recommended resources: Guide for Real Time Clock (RTC) Module with Arduino (DS1307 andContinue reading “Arduino Temperature Data Logger with SD Card Module”

In this project you’re going to build a night security light with a relay module, a photoresistor and an Arduino. A night security light only turns on when it’s dark and when movement is detected. Here’s the main features of this project: the lamp turns on when it’s dark AND movement is detected; when movement is detectedContinue reading “Build a Night Security Light with Arduino”

In this project your’re going to build a web server with an ESP8266 that can control remotely any sockets (safely). Before continue reading this project, please complete the following tutorials: How to get started with the ESP8266 How to Install the ESP8266 Board in Arduino IDE Complete Guide for RF 433MHz Transmitter/Receiver Module With Arduino Let’sContinue reading “ESP8266 Remote Controlled Sockets”

This post is a guide for the popular RF 433MHz Transmitter/Receiver modules with Arduino. We’ll explain how they work and share an Arduino project example that you can apply to use in your own projects.  We have other tutorials about the 433MHz transmitter/receiver that you may found useful: Decode and Send 433 MHz RF SignalsContinue reading “Complete Guide for RF 433MHz Transmitter/Receiver Module With Arduino”

This guide shows how to use an Arduino to decode 433 MHz signals from RF remotes, and send them with an Arduino and a 433 MHz transmitter to remotely control mains switches outlets. Why Decoding RF Signals? I’ve tried different methods of controlling the mains voltage, but some of the methods require: Experience dealing withContinue reading “Decode and Send 433 MHz RF Signals with Arduino”
