A blog about my coding adventures
In previous post, we learned basics of Raspberry PI which is a general purpose, low cost, computing platform. Today, we’ll learn how to install and use Camera module. The Pi camera board is an HD camera, which captures high resolution images. Its pretty much the same camera in your phone. You can use it to … Read more
IoT devices are gaining popularity with every single day. The specialist hardware is becoming standardized and the specialized software is getting abstracted away with the ability to compose our applications using higher-level frameworks. One example of that device is ESP32 and in this post I will give a brief introduction to it. Though the demos … Read more
I like the light-weight programming model of Node.js. I also have great interest in IoT and I have written several posts on that topic as well. In this post, I am going to combine both i.e. IoT device with Node and you will see how natural this binding is. The Internet of things is filled … Read more
Continuing from my previous post on sensors, in this post, I will write about how to do analog-read from Arduino. We will use a photo-cell (also called photo-resistor, LDR etc) for our demo purposes. The photo cell detects the light level, We will use it to measure light intensity using an Analog Input (Arduino) and … Read more
In one of my previous post I briefly talked about sensors and their importance and usage in IoT scenarios. In this post I will write about different type of sensors, their capabilities and usage. Electronic components are discrete device that somehow modify the behavior of an electronic system. Sensors are simply systems of electronic components … Read more
I have previously written about device landscape and IoT. I also mentioned briefly Arduino in that post. I am not going to discuss its hardware architecture, and other theory behind it, more than it is needed. In the reference section you will find links you can check if you are new to arduino or want … Read more
I think you will agree that Internet of things is pretty ambiguous. Any phrase with the word “things” in it is inevitably somewhat ambiguous, right? One of those is “computation that is no longer limited to devices with screens, its far more pervasive, it assumes an eventual connection to the cloud and it integrates into … Read more
An electric circuit is by definition is an arrangement of electrical components connected so that there is some form of current flow. I am assuming you are aware of basics of electronics, so I will keep the discussion about those short and focused. The intention of this post is to laydown the foundation which will … Read more
