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… |

Serial Communication Protocols Before starting with Serial Communication Protocols, let’s break down the terminology into three parts. Communication is a very well-known terminology that involves the exchange of information between two or more mediums. In embedded systems, communication means the exchange of data between two microcontrollers in the form of bits. This exchange of data bits in a… |

RS-485 MODBUS Serial Communication using Arduino UNO as Slave Modbus is a Serial Communication protocol which was discovered by Modicon in 1979 and it is used for transmitting data over serial lines between the industrial electronic devices. RS-485 Modbus uses RS-485 for transmission lines. It should be noted that Modbus is a software protocol and not a hardware protocol. It is divided into two parts such as Modbus Master and Modbus… |

Interfacing Vibration Sensor Module with Arduino There are several critical machines or expensive equipment which suffer damage due to vibrations. In such a case, a vibration sensor is required to find out whether the machine or equipment is producing vibrations or not. Identifying the object which is continuously vibrating is not a tricky job if the proper sensor is used to detect the vibration. There are several types of… |
