Introduction to Microcontrollers - Beginnings
Welcome to this Introduction to Microcontroller Programming tutorial series. If you are looking to learn the basics of embedded programming for microcontrollers (and a bit of embedded hardware design as well), I hope these tutorials will help you along that journey. These are my first postings here, and I am writing this tutorial series because over the years I have seen countless newbies asking the same questions and tripping over the same stumbling blocks, and I thought I might be able to...
Essential Elements to choose a right Processor
Recently I was working for an automotive client where I was supposed to choose a suitable microcontroller for my project. I started listing down the various microcontrollers available in the market, finally I made a big list and it became tough to finalize the best one. Most of the selected controllers were meeting my requirements, and it was really a tough task to choose the right one.
Then I started listing down the aspects...
Intro to Microcontrollers Part 2: AVR Microcontrollers
IntroductionThis is part 2 of my playing around with AVR microcontrollers. Last time, I had a basic setup which could program an AVR using the Arduino ISP. I used it to drive a simple 7-segment, multiplexed 4-digit LED display. This is a follow up where I try out some of the other features the ATTiny24A has to offer. I also decided to invest some money in an AVR Dragon programmer/debugger so I'll go over some basic playing and setup with this device. I'll also discuss some of the problems...
Mounting plate for Arduino
While having a breadboard with your microcontroller is necessary, it is very cumbersome if the two aren't fastened together somehow. You can buy mounting plates, but I choose to make one.
Arduino robotics #3 - wiring, coding and a test run
Arduino Robotics
Arduino robotics is a series of article chronicling my first autonomous robot build, Clusterbot. This build is meant to be affordable, relatively easy and instructive. The total cost of the build is around $50.

Working with Microchip PIC 8-bit Interrupts
This fifth and final post of the Getting Started with Microchip PIC 8 Bit Development series looks at interrupts on 8-bit PIC microcontrollers. After a review of basic interrupt functionality, an actual implementation is explored with the development of a four bit counter driven via Timer0 interrupts whose value is displayed through four LEDs on Microchip's Curiosity HPC Development Board.

How to Design Reliable Reset Circuits for Embedded Microcontrollers
In the world of embedded systems, the reset circuit is a critical component that ensures the microcontroller starts up correctly and recovers gracefully from unexpected events like power fluctuations or software crashes. A poorly designed reset circuit can lead to erratic behavior, system lockups, or even permanent damage to the microcontroller. For embedded engineers, designing a reliable reset circuit is essential for ensuring the stability and robustness of the system.
