IoT Based Electricity Energy Meter using ESP12 and Arduino We all know about Electricity energy meters which are installed in everyone’s house or offices to measure the electricity consumption. At last of every month, many of us get worried about the high electricity bill and we have to look at the energy meter once in a while. But what if we can monitor our electricity uses from anywhere in the world and get an SMS/E-mail when your… |

DIY Arduino Relay Driver Shield In this DIY project we make a 3-Channel Arduino Relay Shield Circuit for relay based applications. We designed an isolated PCB for 3 relays. By using this Arduino Relay Shield, we can operate 3 AC appliances at a time. We have put a two pin screw terminal blocks (Neutral, NO) for connecting appliances. Here we have provided PCB layout, circuit… |

Bluetooth Controlled 8x8 LED Matrix Sign Board Display using Arduino Be it the long stretched highways or your doctors front door, we have sign boards placed everywhere to provide us information. But these sign boards are often boring and cannot be configured as per our interest from time to time. So in this project we are going to build a Bluetooth controlled Sign board using an 8*8 Matrix display. A unique feature of this project is its… |

ESP32 Real Time Clock using DS3231 Module In this tutorial, we will learn about Real Time Clock (RTC) and its interfacing with the ESP32 and OLED display. We will use the DS3231 RTC module to keep track of the correct time and display it on the SPI OLED by using ESP32 as our microcontroller. ESP32 is more than a microcontroller. It has a Wi-Fi and Bluetooth chip inside it and 39 GPIO pins.… |

Arduino RFID Door Lock You have seen RFID Door Lock Mechanism in some Hotels and other places, where you don’t need a key to unlock the room. You are given a card and you just need to put it in front of a RFID Reader box, and the lock gets unlocked with a Beep and a Blink of LED. This RFID Door Lock can be made easily at your home and you can install it in any door. These Door lock is… |

Auto Intensity Control of Power LED using Arduino “Be a bright spark, lights off till it’s dark!” sometimes we forget to turn off the lights and waste electricity and you must have also seen street light turned on in the day. We have already built few circuits on Dark detector where lights turn off automatically if it is bright outside and turns ON if it is dark outside. But this time, in this circuit we are not only… |

How to Program Arduino with an Android device We have built many Arduino Projects and all the time we have used official Arduino IDE to program the Arduino. But do you know that we can also program the Arduino using your Smart phone. Sometimes we don’t have any PC or laptop to program our Arduino boards. We can still program it using our Android mobile, Thanks to OTG (On the Go) adaptor. You… |

Voice Controlled LEDs using Arduino and Bluetooth Controlling LEDs with voice command seems to be a difficult task, but it’s easy and you can quickly build it. We just need an Arduino UNO to serially communicate with HC-06 Bluetooth module and a smartphone to send voice command to Bluetooth module HC-06. For receiving voice command we are using “Arduino Bluetooth Voice Controller” android app which you can download from… |

Arduino Color Mixing Lamp using RGB LED and LDR What if we can generate different colors using a single RGB led and make our room’s corner more attractive? So, here is a simple Arduino based color mixing lamp which can change color when there is change in light in the room. So this lamp will automatically will changes its color according to the light conditions in the room. Every color is the… |

Space Race Game using Arduino and Nokia 5110 Graphical Display Programming has always been fun and it just got a lot better with development platforms like Arduino. Almost every programmer out here would have tried to develop some kind of game using the language that they learning/practising. This helps them to tune their programming skills in a fun yet productive way. I have been a big fan of Arduino ever since I got introduced to it… |

Interfacing Tilt Sensor with Arduino A Tilt Sensor switch is an electronic device that detects the orientation of an object and gives its output High or Low accordingly. Basically, it has a mercury ball inside it which moves and makes the circuit. So tilt sensor can turn on or off the circuit based on the orientation. In this project, we are interfacing Mercury switch / Tilt sensor… |

Bluetooth Controlled Servo Motor using Arduino Using a Servo motor is common in Robotics for precise control. Here, in this tutorial we are going to show you how to use a Servo motor wirelessly with an Arduino UNO and an Android device via Bluetooth connection. We already controlled servo with Arduino, this time we are Controlling Servo Motor using Arduino and Bluetooth. Material… |
