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 […]

Simple Digital Water Flow Meter Circuit using Arduino
In this post I will show how to construct a digital water flow meter using Arduino and 16 x 2 LCD display. We will be taking a look at YF-S201 water flow sensor, its construction and working and how to interface with Arduino to extract some useful readings. The proposed project can measure the rate […]
Joystick Controlled 2.4 GHz RC Car Using Arduino
In this post I will show how to construct a car robot which can be controlled using a joystick on 2.4 GHz wireless communication link. The proposed project is not only made as a RC car, but you can add your projects such as surveillance camera etc. on the car. Overview The project is divided […]
Color Detector Circuit with Arduino Code
In this post I will show how to construct a circuit which can detect color and trigger respective assigned relays. This project is accomplished using TCS3200 color sensor and Arduino board. Color Sensing by TCS3200 If you haven’t read the previous article, please go through it where we have discussed the basics of color sensing […]
Line Follower Robot Circuit using Arduino
In this post I have explained how to build a line follower robot circuit using Arduino, which will run over a specifically drawn line layout and will faithfully follow it as long as it is available and traceable by its sensors. By Navneet Sajwan What is a Line Follower Robot An autonomous robot is a machine […]
Introduction to EEPROM in Arduino
In this post I have explained what EEPROM is, how data is stored on built in EEPROM on Arduino board’s Microcontroller and also practically test how to write and read data on EEPROM by a couple of examples. Why EEPROM? Before we ask what EEPROM is? It is very important to know why EEPROM […]
