ESP8266 as MQTT Client - Arduino IoT Tutorial

ESP8266 as MQTT Client – Arduino IoT

IoT or Internet of Things is an emerging technology which enables us to create a network of devices, sensors, actuators to connect and exchange data. MQTT (Message Queuing Telemetry Transport) is one of the commonly used protocol in this field. It consists of MQTT Broker and MQTT Clients. Where MQTT Broker is the server through which all MQTT Clients are communicating each other. CloudMQTT provides MQTT Broker as a service, which we are using in this tutorial. In this project we...

System Configuration - OpenWrt

How to change Hostname of OpenWrt ?

Sometimes you may need to change the hostname of your OpenWrt. Host name is stored in the system configuration file. You can view it in the following command. cat /etc/config/system System Configuration - OpenWrt It is very easy to change hostname of OpenWrt, using following commands. Here we are changing our hostname to "electroSome". uci set system.@system[0].hostname='electroSome' uci commit system /etc/init.d/system reload Changing Hostname of OpenWrt

Interfacing PIR Sensor with Arduino - Practical Implementation

Interfacing PIR Motion Sensor with Arduino

A PIR sensor is generally known to the world as a motion sensor or motion detector. So in this project we are going to use the PIR motion sensor to detect motion. Here we are going to sense movement of human by using Passive infrared sensor (PIR sensor). Using the feedback from the sensor we will control an LED with the help of Arduino Uno.
