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 […]
Newly Updated Circuit Projects:
Mobile Phone Controlled Robot Car Using DTMF Module
In this project we are going to control a manual robot through our cellphone using DTMF module and Arduino. By: Ankit Negi, Kanishk Godiyal and Navneet Singh sajwan INTRODUCTION In this project two cell phones, one for calling and one for receiving the call are used. The phone receiving the call is connected to the robot […]
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 […]
Password Controlled AC Mains ON/OFF Switch
In this post I will show how to construct a password based mains ON/OFF switch circuit, which can turn ON and OFF the AC mains supply, only when correct password is entered. This prevents the danger of electrocution of the technician who might be currently working with the high voltage lines and equipment. Password Protection […]
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 […]
L298N DC Motor Driver Module Explained
In this post I have explained about L298N dual H-bridge DC motor driver module which can be used to drive brushed DC motors and stepper motors with microcontrollers and ICs. Overview Modular circuit boards are best time savior for electronics designers which also reduce the prototyping errors. This is mostly preferred by programmers who write […]
