Which feature of RGB LEDs has made them an attractive and practical component in Electronics and Lighting Industry?Answer: Their unique feature of regulating the ratio of the three primary colors (red, green, and blue) to generate a desired color with one LED. An RGB LED has a common pin as well as three pins for red, green, and blue colors. We can combine these primary colors to generate countless colors by controlling these pins with a PWM pulse signal. (The number of colors changes depending...

Most people reading this article are probably familiar with Arduino or at least have heard the name. In this article, we try to introduce this platform in more details and study it from a critical point of view. Furthermore, we will point out the features we have come to discover in our experiences that have not been appropriately addressed. In the first section of the article, we discuss Arduino’s past, why and how it came to life and then study its components. In the second section, we b...
Overview
Suppose you want to make a 4x4x4 LED matrix. You will need 64 digital pins to control such an LED matrix. So, it would not be affordable if you decided to choose a microcontroller which has that number of digital pins. So, what is the alternative? In such cases, the most suitable way is to use a shift register to increase the number of digital pins of your microcontroller.
Increasing the number of digital pins of microcontrollers is among the most attractive and practical topics. In many applicatio...
