Buck Converter Circuit Using Arduino

Last Updated on October 30, 2025 by Swagatam 22 Comments

pwm

In this project we are going to step down 12 V DC to any DC value between 2 and 11 V. The circuit which steps down the DC voltage is known as buck converter. The output voltage or step down voltage needed is controlled using a potentiometer connected to Arduino. By Ankit Negi INTRODUCTION TO […]

Introduction to I2C LCD Adapter Module

Last Updated on September 18, 2025 by Swagatam 4 Comments

IIC

In this post we are going take a look at “I2C” or “IIC” or “I square C” based LCD adapter module, which will reduce wire connections between Arduino and LCD display to just 2 wires, also saving tons of GPIO pins for other sensors / drives etc. Before I have explained about I2C LCD adapter […]

Vehicle Speed Detector Circuit for Traffic Police

Last Updated on September 14, 2025 by Swagatam 3 Comments

setup

In this post I will show how to construct a circuit which can measure the speed of any vehicle on roads and highways. The proposed circuit is kept stationary at a place where the vehicles are suspected to over-speed. If any vehicle goes beyond the speed limit, the circuit alerts immediately. We will be looking […]

Arduino RGB Flowing Sequential Light Circuit

Last Updated on September 10, 2025 by Swagatam Leave a Comment

rgb 3

In this post we are going to make a simple but useful circuit that can make an RGB LED glow in a nice flowing way. That is not just random blinking, but smooth sequential lighting of red, green, and blue one by one. This is done using Arduino, so you need to have some basic […]
