Where To Go After Arduino? 2 Paths For You To Pick From!

Arduino is a lovely little ecosystem where most of us have started our electronics journey. I still remember the moment I got my first LED blinking program working! Since then we have done several projects using Arduino. Some of those we by following some online tutorials while others were produced out of our own ideas with a little bit of online research. But there comes a point in every inventor’s journey where we have simply outgrown Arduino. If you are reading this post then you are at the same place where I was some years back. I wasn’t sure where...

Hardware, Software, Firmware, Middleware, Drivers, OS & Applications, The Difference?

We hear a lot of these “wares” terms all the time, some are hard, some are soft, some are firm and some are in the middle. But why some many types of wares? How do they all fit in? Let’s learn more about them in this article. Let’s start with the familiar term hardware. Hardware What is Hardware? Hardware is a system consisting of electronic devices, designed to work together as a single unit. It is the only tangible “ware” out of our list that you can physically interact with. Examples include PCBs like motherboard, RAM, Integrated Circuits, Processor, Microcontroller,...

Quad-SPI, Everything You Need To Know!

If you have just mastered this SPI interface, then looking at Dual and Quad SPI can be overwhelming. I had to read several pdfs to wrap my mind around this concept. In this article, I am presenting all the useful and interesting facts on Quad-SPI that I have learned through my research. What is Quad-SPI? It is a serial interface, where 4 data lines are used to read, write and erase flash chips. Quad-SPI Quad-SPI, also known as QSPI, is a peripheral that can be found in most modern microcontrollers. It has been specifically designed for talking to flash chips...

200 Embedded and IoT Software Engineering Interview Questions – Part 1

I remember the time I was actively looking for an embedded software engineer job as a fresher, I was looking for some good resources to test my skills, but I found only a very few useful ones and that too not directly related to embedded engineering jobs. I am writing this article to serve that purpose as a good resource to test yourself before you go for embedded engineering interviews. Usually, any technical interview will have questions from these 3 categories Questions about yourself Questions about the projects you have done Questions to test your subject knowledge I will only...
