LIGHTING UP AN LED

Image
Hi to all of you! We learned the fundamentals of microcontrollers in the last post. Today, let's get introduced to LED , one of the most crucial electronic components, and how to use them. OHM'S LAW   Knowing Ohm's Law is essential before beginning any electronics course since it forms the foundation of our comprehension of the relationship between voltage, current, and resistance. Picture taken from build-electronic-circuit.com     Take a look at the image above. Think of Voltage as the pushing force which results in the movement(current).  The faster you push; the speeder will be the movement. That is,             Current  ∝  Voltage   The opposition provided to the current flow is known as the resistance, and it is measured in ohms. Even with increased voltage, current will be lower when resistance is higher.            Current  ∝  1/Resistance   Combining the above two ...

WELCOME TO THE WORLD OF MICROCONTROLLERS!

 Hi to all of you! This is my first blog post about the Arduino electronics series. We will discover a plethora of fascinating information about Arduino in this series. Don't worry if you've never worked with an Arduino or other microcontroller before. Every concept will be started from scratch. Thus, NO PREREQUISITES! Without any further delay, let's get started.   Microcontroller   Let's attempt to gain an intuitive grasp of the functions and principles of a microcontroller. Consider it as an all-purpose calculator that can perform any computation task that is thrown at it. When represented as a block diagram, we can say:    In the example above, we are providing an instruction to the microcontroller to add two numbers (ADD 5 & 6). After that, the microcontroller decodes the command and outputs the result. The example above highlights three important ideas for us to comprehend.               1)  Instructions:...
