Mongoose OS Installation on ESP8266 and GPIO Access

mongoose OS

This video is around ESP8266 module and how to flash mongoose OS to it.It also demonstrates some basic GPIO programming using javascript.Mongoose OS claims as an Operating System for commercial connected products with features like Security, OTA Updates, Remote Management. As Arduino framework is not reliable to run in production environment its a good alternative with  Arduino compatibility layer that allows using existing Arduino drivers for prototyping. It is both C/C++ ready for production and  JavaScript is for fast prototyping on the target hardware. The JS API calls C API.…

OpenHAB: Installation on Windows for Home Automation

OpenHAB on Windows

OpenHAB is a vendor and technology agnostic open source automation software for making home automation easier. This video is around how to get started with OpenHAB 2. In fact, this is going to be a series of video around it as I have completely shifted towards OpenHAB for my home automation system. Earlier actually I was using my own automation system built on PHP, JAVA, and MongoDB and it was becoming hard for me to manage that and so I thought of getting into already existing automation system and with…

IOT With Raspberry Pi using JAVA

IOT_Pi

This post features videos that I published to my YouTube channel in the series “IOT with Raspberry Pi “. This basically contains 4 videos around raspberry pi that show how to use Raspberry Pi as an IOT device. It starts from interfacing sensor to publishing the sensor data to cloud server using protocols like REST or MQTT. For the entire project I have used JAVA and on top of that used various libraries for specific tasks like Pi4J, Unirest, Eclipse PAHO etc (Links provided below). If you have watched any of the videos you…
