## Tips For Sampling High Speed Analog Signal in Arduino/Microcontroller

In many Arduino projects, we need to sample high-frequency signals such as an audio or equivalent signal. Think about a situation we want to sample the 50Hz AC signals and want to see the signal in Arduino serial plotter in real-time. In such cases, we make a few common mistakes that can be easily avoided …

## Custom data structure design for Arduino and Microcontroller project | Part 1

Data structure provides an efficient way of organizing data and functionality in the digital system. Good data structure design makes the system efficient and fast. There are few standard data structures in computer literature. Queue Stack Array – One dimension as vector Array – Multi dimension as Matrix List Tree Apart from the standard data …

## Power Factor Improvement Plant Using AVR Microcontroller | PART:02

The most challenging task  of this project is to determine power factor. Rest of the tasks are just switching Relays. So our first target is to find power factor using algorithm given in our first tutorial “Power Factor Improvement plant using AVR Microcontroller | Part:01“ Before we proceed to download the project files and open schematic …

## Power Factor Improvement plant using AVR Microcontroller | Part:01

Power Factor: Voltage and current are always in phase for the resistive load.But for inductive load voltage always leads current & for capacitive load current leads voltage. Power factor is the cosine of the phase difference between voltage & current. Power Factor Improvement: Power factor Improvement is minimizing the phase difference between voltage and current …

## Microcontroller Introduction

After Inventing Transistor in 1948 and Integrated circuit in 1960, a revolutionary change came into circuit design. People started solving real life problems using analog electronic components like Transistor, diode,OP-Amp  etc.After a while people realized solving real life problems, circuit requires some qualities.such as:  Arithmetic calculating ability, Decision making ability,  Time measuring ability Data saving …
