How to Use BH1750 Ambient Light Sensor with Arduino When you take your phone in sunshine or in high lighting, then it automatically adjusts the brightness according to the lighting conditions. Most of the display devices now a days, whether it’s a TV or mobile phone, have the Ambient Light Sensor inside to adjust the brightness automatically. Today in this tutorial, we will use one such sensor BH1750 Light Sensor Module… |

RS-485 MODBUS Serial Communication with Arduino as Master In the previous tutorial we learned about Modbus RS-485 Serial Communication with Arduino as Slave. In continuation with that article today Arduino will be used MODBUS Master and communicate with MODBUS slave. Here MODBUS Slave Software installed computer will be used as MODBUS Master. So, let’s begin by a short introduction about the RS-485 and Modbus. … |

Joystick Game Controller using Arduino Leonardo We previously interfaced Joystick with Arduino UNO to understand how it works and controlled four LEDs on its left, right, up and down movement. In this project we will use the same Joystick as Gamepad or game controller to play any computer games which requires left, right, up and down movements. To play games which requies more control options, two or more joysticks can be… |

DIY Arduino Based Color Sorter Machine using TCS3200 Color Sensor As the name suggests, color sorting is simply to sort the things according to their color. It can be easily done by seeing it but when there are too many things to be sorted and it is a repetitive task then automatic color sorting machines are very useful. These machines have color sensor to sense the color of any objects and after detecting the color servo motor grab… |

IoT Based Biometric Attendance system using Arduino and Thingsboard Few years back if you were to tell someone that the Geyser and bedroom lights in your home are connected to internet, they would be baffled and might even criticize it as over-engineered products. But today with the advent of IoT, Smart cities etc the idea no longer sounds strange, we have devices around us that have become smarter by being able to communicate with the… |

Programming Arduino using Platform IO Development in Arduino and Arduino IDE has always been easy and fun with their simple user interface. The Arduino IDE is open-source and free to use Development Environment with all features like write, compile and upload the code to Arduino Boards. It is based on Java and runs on major OS like Windows, OS X and Linux. But with all its simplicity and large community, it… |

Interfacing GT511C3 Finger Print Sensor (FPS) with Arduino Biometrics has been used as a reliable authentication system for a long time now. Today there exist complex biometric systems which can identify a person by his heart beat rhythm or even by his DNA. Other feasible methods include voice recognition, Face recognition, Iris scanning and Finger print Scanning. Out of which the finger print recognition is the most widely used… |

Node.js with Arduino: Controlling Brightness of LED through Web Interface We have seen numerous examples of Blinking an LED using different Microcontrollers and different programming languages. Today, we will use a very popular JavaScript framework Node.js to control the LED connected to Arduino Uno. We will also use Node.js to control the brightness of LED from a webpage using Arduino. By few tweaks and using ESP8266, this can be converted… |

LoRa with Raspberry Pi – Peer to Peer Communication with ArduinoLoRa is getting increasingly popular with the advent of IoT, Connected Cars, M2M, Industry 4.0 etc. Because of its ability to communicate to long distances with very less power it is preferably used by designers to send/receive data from a battery powered Thing. We have already discussed the basics of LoRa and how to use LoRa with Arduino. Although the technology is originally intended for a LoRa… |
