In Part 1, we created a device policy and a thing on AWS IoT core. In this article, we will use the downloaded certificates to connect to the MQTT broker to publish messages and subscribe to topics. We will use the PHP-MQTT library. AWS IoT core uses...
AWS IoT core provides a suite of features that makes connecting IoT devices to the cloud and managing them a breeze. An MQTT broker is one of the services offered by AWS IoT Core. In this 2-part series, I will go over creating an IoT device or thing ...

Recently, I have been experimenting with MQTT, a lightweight messaging protocol that is designed to provide efficient, reliable, and real-time communication between devices and applications in machine-to-machine (M2M) and Internet of Things (IoT) con...
Like many others, I learned of Arduino very early when I was learning about embedded systems. It felt great to be able to build pretty complex projects like a remote-controlled fan without much of a more profound knowledge of electronics and the best...
Once I started trying to follow online tutorials to build electronic projects, I quickly ran into an issue of finding where I can buy these modules and electronic components. I wanted to find local shops that I could buy from since shipping everythin...
