IOT With Raspberry Pi using JAVA


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…

Programming Onion Omega 2 using Python | GPIO Access

Onion Omega Python

This tutorial is all about developing python applications on Onion Omega 2. As the onion omega doesn’t come with python pre-installed, we need to install it ourselves. We can write a variety of scripts using python for Omega 2 and most importantly for IOT application we can access the GPIO of omega 2 by using python itself. So let’s check out how to do that. And if you are unaware of what is onion Omega 2 you can check the official website for more details and even buy one to…
